SOURCE: Sending DHCP request across diffrent vlans

Hmm... on your DHCP server, try setting the "default router" IP for each pool to be the VLAN ID on the switch.

scope 172.16.0.0 /24
router 172.16.0.1

scope 10.20.8.0 /22
router 10.20.8.1

I think the DHCP replies aren't going back where they should. I've never done this without a router doing all the DHCP, but it does work and i've done it many times. Your config looks spot on for the switch.

WHAT ARE THE PORT RANGES FOR ADDRESSES


Usable tcp and udp ports range from 1 to 65535. However you should not need to open any ports by default. Most routers include a stateful packet inspection (SPI) firewall. This is a fancy way of saying the router inspects the packet on it's way out to the internet when a computer on the inside of the firewall sends it out to the internet. The firewall will only allow connections from the internet on that TCP or UDP port if it returns from the original destination. For example, if you send a packet requesting the web page at cisco.com, the firewall will only allow traffic back into your network on TCP port 80 from the web server at cisco.com. If a packet from any other IP address tries to piggyback into your network through tcp port 80, the firewall will block it.

The only reason to open ports on your firewall is to allow a server inside your network to receive unsolicited traffic e.g. a web server inside your network may need TCP port 80 and 443 (HTTP and HTTPS) opened if you want to be able to access it from the internet. A mail server may need port 25 and 110 open for SMTP/POP e-mail. However, most home users do not host their own mail or web servers.

How to connect wap4410 with pc to confgure


Try disconnecting your Cisco Wap4410 from all other network devices then restart it - it will look for a DHCP server, and when it doesn't find one will choose the IP: 192.168.1.245 ---
Set the TCP/IP settings on your laptop to:
IP:192.168.1.250 / Subnet Mask: 255.255.255.0 / Default Gateway: 192.168.1.245 and connect your laptop ONLY to the WAP4410 using a cat5 ethernet cable ---- you should then be able to load a web config page using internet explorer and browsing to: http://192.168.1.245
-------- I've paraphrased the following info from the Cisco User Support Forum (User Juunda):
"...If you read the administrator guide it states that the WAP4410N will search for a DHCP server first, if the dhcp request times out then will it default to 192.168.1.245 this is done so with a user friendly plug and play mentality in mind. Best practice would be to give the AP a static IP of your choice and in your subnet/network so the fastest way to configure the AP out of the box is to assign a static IP on your pc/laptop in the 192.168.1.X /24 and directly connect to the WAP4410N and give the WAP a static IP, define your gateway, DNS servers and then implement it into your network..."

The problem could be that the static IP address is not in the range as the IP address as the router.
You should let the wireless router issue an IP address to your computer.
Change the TCP/IP settings in your laptop's wireless card to Obtain an IP address automatically and Obtain DNS server address automatically.
Then reboot your laptop.

Wireless connection goes of then will not connect


Hi
I get that you was connect to the internet by wireless connection .
so in you connect with access point connected directly to dsl modem so try to restart the access point and try to connect again ...and reset the wireless in your device... may be it works .

I think this problem occur cause access point or DHCP server cant give your device new IP address..
so you must clean the DHCP leased addresses by restart the access point or enter to server and do that from DHCP .

else you can try to assign static ip address has the same network id with router ..
for example : if router ip is 192.168.1.1 so you must assign ip address like :
192.168.1.x while x number between 2 and 254
hope that helps you

To Configure the Router with Internet Access

Connect to one of the wireless router/access point's LAN Ethernet ports, turn off its DHCP server, and give the wireless router a static IP on your LAN:

  1. Connect a PC directly to a LAN port on the wireless router with an Ethernet cable.
  2. Power on the wireless router/access point.
  3. Reboot the PC.
  4. Log in to the wireless router though a browser. (Usually 192.168.1.1, with User Name = admin and Password = password, unless you changed them from the defaults).
  5. Go to the LAN IP menu and disable the wireless access point's DHCP server by unchecking Use router as DHCP server.
  6. Select LAN IP, and change the IP to 192.168.1.99.
  7. Click Apply to save the settings. You will lose the connection to the wireless router/access point , since its IP changed.
  8. Log in to the wireless router/access point with the URL: http://192.168.1.99
  9. Connect one of the wireless router's Local (LAN) ports to your existing network

Ip address for clients using autonomous cisco 1130ag witout dchp


the cisco1130ag will provide ip addresses and serve as a DHCP server for your laptops...

You still need an IP address for your 1130ag so either your ISP provides you a static ip that you can put in the 1130 or if your ISP provides dhcp then you should be able to plug and play with your 1130ag

Can't access my DSC 950G security camera


you have to log into the main IP address, not the camera IP address. If you are using wireless, the camera will have an IP address different than the one for the router coming from the ISP.
I just bought this camera myself and am trying to work out the kinks. My ip keeps changing and i am not sure how to keep it the same, static?

DLink DI-624s - can't get Cisco VPN Client to connect.


The "Virtual Server" setting is designed to give the general public access to a network resrouce (web/ftp/media server) on your internal network. If your the VPN concentrator is external to your network (meaning you'll have to use the internet to connect to it), then you won't need to define a virtual server on the DI-624.

You'll just need to enable the IPSEC and PPTP VPN Passthrough which it sounds like you've already done this. I've run into some ISP's that block VPN connections out of their network. If you have the ability, try to directly connect your laptop into your cable/DSL modem in place of your router and see if you can make a VPN connection, if not contact your ISP, if you can then verify you enabled the VPN passthroughs because your router is blocking them.

GIve it a shot and let us know your results.

RCA Modem DCM315R


Just a bit of explanation. E0 interface is for inside network (LAN interface). E1 is for outside (ISP or WAN physical interface). Dialer1 is for PPPoE (the "actual"/logical WAN interface). The 1.0.0.13 is ISP provided static IP address for the use of the server. This configuration example is for running FTP server, which uses the standard TCP port 20 and 21.

The LAN uses 10.10.10.0 network with 255.255.255.0 subnet for both servers and workstations. All servers within the LAN use static IP address. The router is configured as DHCP server to give out IP info (IP addresses, subnet mask, DNS) to workstations that are configured as DHCP client.

Basically I suggest that you deploy NAT (Network Address Translation) and PAT (Port Address Translation) to setup your own servers behind Cisco router. The NAT is used to translate the ISP's given static IP address to your local IP address. The PAT is used to translate TCP ports (the port 20 and 21) between the two IP addresses.

When using NAT/PAT, keep in mind that the Internet-accessible servers are seen from the Internet as their NAT/PAT-ed IP address (the Public IP address) and not the local IP address (not the Private IP address). This understanding is very important when you or someone need to test connectivity to the server and/or when you need to create filter (access list or ACL for short) to allow only certain incoming traffic from the Internet and block others.

Side Note:
For more info on NAT/PAT concept, check out the following FAQ
»Cisco Forum FAQ »NAT and PAT; Introduction and Implementations

Instruments used in this illustration are pretty much standard for running your own servers. Please note that IP addresses, username, and password are changed. However, you could always modify the configuration to suit your situation.

This sample configuration assumes that you have a block of IP from ISP. There is a dedicated Public IP address for the router WAN interface (the Dialer1 interface) and another dedicated Public IP address for the server PAT IP address. If you only have a single Public IP address for both router WAN interface and server PAT IP address, there are several ways to configure the router.

One way is to use the same command as shown in sample configuration.

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
ip nat source static tcp 10.10.10.2 21 1.1.1.14 21 extendable
This one configuration way is suitable when you have static IP address from your ISP and you know exactly what the IP address is. In this case you have the 1.1.1.14 single static IP address for both the WAN interface and Public server IP address.

When you are unsure which IP address you receive from the ISP, or when your Public IP address keep changing; then another way to configure the static PAT is following

view plaincopy to clipboardprint?
  1. ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
ip nat source static tcp 10.10.10.2 21 interface Dialer1 21 extendable
With situation of dynamic IP address, at some point you still need to know the exact Public IP address you receive from your ISP for server connection testing and production time. To find out, you can issue show ip interface brief command on the router. You will then see the associated WAN interface Public IP address.

Router cannot get IP with cisco 675 modem


Hi,

The issue may be due to the existence of two (2) DHCP servers; 1 in the Cisco 675 and the 2nd in the DLink DI-524. You need to disable the Cisco's DHCP server function and assign static IP add & config to the DLink WAN config. This way it will only be the DLink handing out IP adds to the network.

The workaround. Install your original configuration/setting without the DLink DI-524 - PC direct to the Cisco 675 (I am assuming through Ethernet ports). Verify that indeed you are connected to the Internet and can surf the net, check e-mails, etc. Check your Networking Connection Status. Log down your PC's IP Add, Subnet Mask, Default Gateway, DNS. For purposes of discussion, let's call this "N1".

After your Internet connection has been verified with your PC directly connected to the Cisco, remove the direct connection and connect the DLink DI-524 in between the Cisco router and your PC.

Log in to the DLink and modify WAN parameters using the "N1" configurations/settings.

It might be of help to disable any security (WEP WPA, MAC etc) at least while configuring.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
