The subnet mask

Hi

my problem is that I can`t get in to some internet sites. I wonder if it is the subnet mask that causes this problem? the numbers it writes is 255.0.0.0 is there any way to cange theese numbers?

By the way, is there a way to adjust the settings for where the router considers something to be a synflood. (I am using torrents and I believe the router mistakenly considers heigtened networkaktivity for a synflood attack)

    well I found out that upgrading the firmware solved most of my problems. after upgrading I could access the internett pages I couldn`t before, and there were some new settings I could cange (preferd DNS settings and the router subnet mask) only problem that remains is that it mistakes some of my internett traffic as synflood. I`ve found where I can cange som settings that relates, but I don`t know what they mean exactly. (increasing / decreasing ) Eevery morning someone have managed to shut down my service so I need to reboot the router. for eksample I`ve been getting a lot of "smurf":s and IP-spoofing and different kinds of packet flooding.

To change you subnet mask, go to control panel. look for network settings. select your internet. Right-click and properties. Look for subnet mask options (Try TCP/IP) If your subnet mask settings arent on automatic, put it to auto, if they are on auto, manually type in 255.255.255.0 (That is what is supposed to be)

Hi...getting "LOCAL IP ADDR INVALID" on one of my INTER-TEL PHONES....82622V2


Bill
what about the sub net mask is it exactly the same as the others ?

Has the subnet mask been used to create a separate network ?
what is the subnet mask ?
is it 255.255.255.0
does it have numbers in it that are not 255 or 0 ?
if the number is different to this you have subnetting on your network and may need to use a particlar ip address to fit into the subnet.

How do i establish a subnet with a A address


The subnet is determined by the subnet mask. Class A addresses are contained in the following range: 0.0.0.0 - 127.255.255.255. The most common use of a class A address is 10.0.0.0

In class A networking you may use a subnet mask from 255.0.0.0 all the way to 255.255.255.255

The subnet would work as the following example:

Network Address: 10.x.x.x
Subnet mask: 255.0.0.0

The first number in the above example would determine our subnet. So if you have 2 devices and you would want to put them in a different subnets you would want the first octet (octet is each number seperated by periods) to be a different number.

Network 1: 10.x.x.x
Network 2: 11.x.x.x

Unless these devices use a router to communicate they would not "talk" properly. Thus giving you 2 different subnets.

Hi. i cant connect to print server d-link dp301p+ IP to configure it?! who knows what IP by default it have? 192.168.0.10 doesnt work... Thanks, Mike


First find out the IP address , Subnet mask,and Gateway addresses of your ISP ( Internet Service Provider ). According to above addresses, you have to complete the network settings of your printer by mentioning the different IP address .

To find out the above mentioned addresses, first open the control panel -> network connections -> local area connction -> properties -> Internet Protocol Version 4(TCP/IPV4) OR Internet Protocol Version 6 (TCP/IPV6)according to your ISP -> Properties

By the systematic selection as mentioned above you will get the IP address, subnet mask and Gateway addresses.

Suppose your IP address is 192.168.0.10 , the gateway may be 192.168.0.1 Or any number. And the subnet mask may be XYY.XYY.XYY.0.

According to your ISP addresses you have to complete the network settings of your printer. First press the additional functions -> system settings -> network settings -> TCP/IP settings -> fill up the addresses as follows.

IP address : 192.168.0.16 OR any number .

subnet mask : XYY.XYY.XYY.0.

Gateway : 192.168.0.1

Hurray ! the problem about your network connection with the printer to your computer will be automatically solved.

When i write hhtp://dlinkap on the explorer internet i have nothing


Hi i believe that you do have dlink access point device...
if the http://dlinkap doesn't work, try to asign STATIC IP to your computer

assign the following:
IP address:192.168.0.55
Subnet mask: 255.255.255.0
Default gateway: 192.168.0.50

the try to access again the http://dlinkap or simply typein 192.168.0.50

and thats it you're now in the login page of the access point device.

hope this will help

I cannot get my Wii to connect to my 2wire router. We have not been able to connect ever since we switched to ATT. Please help.


I had a similiar problem; check your PC settings and find out your IP address, subnet mask, default gateway and DNS settings and write them down. (from "run", type "cmd", then in the window type "ipconfig /all")
if your IP address is (for example) 192.168.1.1 mask 255.255.255.0 and gateway is 192.168.1.254, go to your Wii settings and change the internet settings to NO DHCP, give the Wii an address of 192.168.1.10 with the same subnet mask, default gateway and DNS server setting as your PC. Remember the FIRST 3 numbers of the IP address must be the same and the last one DIFFERENT.

Error code 8002ad23


Hi Giles

You probably have your router connected to your modem, and a PC connected wired/wireless, and the ps3 connected wired/wireless.


1. First you need to start your ps3 system. Go to your network settings and select information. Write down your IP, Subnet mask, Standard Gateway, and the primary DNS.

2. Start your PC and go to your networks settings. Right click your network adapter, click properties. Select "Internet Protocol version 4 (TCP/IPv4). Click properties and type in manually the IP adress, Subnet mask, Standard gateway and DNS.

Then you click "Advanced" and then you click "WINS" then "Activate NetBIOS over TCP/IP". Save your settings and connect the ps3 to your network (should not make a difference if you do it wired or wirelessly)

Let me know if this helped and please do rate my solution.

I can't get my computers to talk to one another through sonicwall and Im wondering what could be the issue


THere are many things you must be fully educated on like DNS, IP numbering and subnet masking for different networks (for the different sites), TCP Port and Protocol (UDP, TCP) knowledge for different TCP services (you have to know what you want each network to have access to) and Public Key Private Key methodology, IPSec, PPTP and Routing.

THere are many things that can go wrong. FOr instance in your particular case I would assume that your router is not configured to utilize groups of users and then assign those same groups to different traffic templates. YOu need to make sure that your four locations are assigned a particular traffic pattern. Most allow what the other gentleman spoke of "remote access" but you need more of a open network amongst authenticated users.

Routers of this class generally work by allowing you to assign traffic to a very specific Port and direction assignment. For instance simply - http traffic is always on port 80. If you wanted your users to have internet HTTP connectivity you must assign port 80 incoming and outgoing to those users and assign that traffic to internal and external IP addresses by using Network Address Translation on the IP address of the external network. YOu also want to make certain that your Gateway for the remote users are using their own internet service provider account because sometimes uneducated people setup the internet access to be routed to the external ip adddress on the home router. In this situation you would have a remote user dialing the home office and then requesting an internet page from that External network, only to have that traffic then come back to the home router and then out again over the vpn to the remote location. All internet traffic should be routed to the local gateway of that locations provider. THose remote routers will allow this and then only file sharing and printing and other critical network services should be routed over the VPN itself.

As I said it is very complicated and I would definitely pay someone to do this for you and then walk you through basic configuration issues while they are there. You would probably pay in the neighborhood of about 100-150 an hour but for this level you would be getting a certified and knowledgable person. You could also call SonicWall and have them walk you through it for a fee. Watchguards fee is 500.00 to 1000.00 depending on sophistication.

I am sure this only confused you more but IP Routing and VPN traffic routing is difficult and even people who have been in this industry for a very long time find it difficult. You have to be in it and doing it all the time for it to come second nature. I believe your IP addresses are on completely different subnets or ranges. That is another place to start. You really need to setup your internal networks at all locations on the SAME NETWORK in order for them to speak to one another.

127.0.0.1 is one network that is publicly unroutable or 192.168.0.1 or 192.168.111.1. These are common netoworks.

I'll try to give you a short lesson this. subnet masks (the 255.255.255.0) number under the ip address in the networks section allows you to segment your traffic to only communicate to a certain NUMBER of computers.

An IP Address of 192.168.0.0 with a subnet mask of 255.255.255.254 gives you zero computers. If you move the subnet mask to 255.255.255.252 you get 4 ip address but only 2 computers that can talk to one another. THe ip address in this configuration would be 192.168.0.0, 192.168.0.1, 192.168.0.2 and 192.168.0.3. The first ip address of any given network is ALWAYS the network address and should not be used (192.168.0.0) the next two ip address can be assigned to computers and the last ip address is always a "Broadcast" address for the network to speak on.

YOu could have started with another number to begin with for instance 192.168.1.54 subnet mask 255.255.252 and the same methodology would apply. 192.168.1.54 is the network, 192.168.1.55 and 56 are the computer addresses and 192.168.1.57 is the broadcast address.

If you want to have multiple computers at different locations you must all be on the same network with the same IP addressing scheme.

AN example 192.168.111.0 subnet mask of 255.255.255.0 would give you available address of 254 computers but 256 addresses (including zero).

The subnet masks are as follows for this network above (maybe you can use this)

192.168.111.0
255.255.255.254

Zero Computers only a network address and a broadcast address. Remember you only have 256 addresses in a range and the first is network and the last is broadcast so in this configuration you have 192.168.111.0 and 192.168.111.1 (only two addresses)

192.168.111.0
255.255.255.252

Two Computers 192.168.111.1 and 192.168.111.2 with network of 192.168.111.0 (first IP number) and broadcast of 192.168.111.3 (last IP Number) only two usable addresses but FOUR ip addresses.

192.168.111.0
255.255.255.248

Six computers with IPS of 192.168.111.1 to 192.168.111.6. Network of dot zero and broadcast of dot seven (192.168.111.7)

192.168.111.0
255.255.255.240

fourteen address 192.168.111.1 to 192.168.111.14
network .0, broadcast .15

subnet of 255.255.224
thirty computers 192.168.111.1 to 192.168.111.30
network of .0 and broadcast of .31

subnet of 255.255.192
sixty two computers 111.1 to 111.62
network of .0 and broadcast of .63

subnet of 255.255.128
One hundred twenty six computers 111.1 to 111.126
network of .0 and broadcast of .127

subnet of 255.255.0
Two hundred fifty four computers 111.1 to 111.254
network of .0 and broadcast of .255.

THis is one reason the actual computers wont talk to one another probably. ALL computers on the VPN must talk on the same Route or be ROUTED with the routers routing of networks options. to make the traffic move from one network to another.

Cannot connect to internet


Make the Ip address similary to the router, example 192.168.1.25 should work.
SUbnet mask will then fill in automaticaly, just leave it
then Default gateway will be the routers IP. 192.168.1.1
the dns server would be the ip of your internet provider. I would leave it blank at first, see if it will work then. If not, then ask your service provider for it. If they give u a number, then you will have to go into the router properties, and change the dns and stuff like that in there aswell.
good luck

Adding additional computer problem


Yes, the xp machine connects to the net. DHCP is not enabled. The ipconfig/all command brings up the correct static ip address, subnet mask, and default gateway. But it does also say under the ip configuration that ip routing is not enabled. I did have the 2000 machine connected when I first set up the router yesterday, but I booted up my laptop to try to set up a wireless connection, and then I had to reinstall the entire router set-up.

Changing the IP address


check with the manual of the server that it is having web based management. If yes make your computer ip and subnet mask as per the ip and subnet mask of print server. open the internet explorer type the url as specified in manual enter the username & password as per manual. there will be the setting page displayed where you van change th eip of the print server. if not please write me which type of management it uses to access the settings.
