Question about Computers & Internet

1 Answer

I am trying to telnet through a Linksys RVS4000 from the wan side of the router to a fixed device on the lan side of the router. Both networks wan & lan are operational and I can ping the Wan side of the router from the P.C. that I want to open telnet on. I have setup both port forwarding in the RVS4000 and pointed port 23 directly to the IP address of the lan device. I have also set the RVS4000 Firewall with an IP based ACCESS list of wan and lan IP addresses that are allowed to pass through. I have updated the RVS4000 firmware to the latest version from the Cisco/Linksys website. When I run telnet and open the telnet session to 10.0.0.3 (the IP address of the Wan), I get a can't open connection to the host error. What am I missing? Thanks

What does the LAN do on the modem


There are two halves to a router. The internet (WAN) side a local network (LAN) side.

The term WAN means Wide Area Network and generally refers to the internet.

The term LAN means Local Area Network. That would be for the computers that are in your office or home.

The LAN connects your computer to your printers or to other computers.

I hope that answers your question!

Your only mistake here is what port you are using on the ASUS. Only modems connect to the WAN port. Connect one of the Linksys LAN ports to one of the ASUS LAN ports. What you are essentially doing is using the ASUS as a wireless access point rather than a router. Additionally, you may have problems if you try to use the same wireless network name and password on both devices. Better to assign a different one to the ASUS and just let devices connect to whichever signal they find strongest.

How do I telnet to linksys E900


Windows XP included a 'telnet' client.
With Windows Vista/7/8, you have to explicitly choose to install the 'telnet' client.
Then, you can use the 'telnet' command.

Linksys router connects and says it has an excellent signal but will not aquire an address please help


Try a hardwire computer and get into the setup page of the router by typing 192.168.1.1 on your browser . Make sure you have changed the SSID or the network name of your router to your choice. Check if you have security set. If you have one make sure they match your computer.

Linksys RVS4000 Networking question


it seem that your best bet would be to look into remote access programs that can be found easily on google.com. I would suggest browsing some of the options you find on there.

Vpn


this is not so much a soloution but an idea!
from memory the netopia devices allow you to configure a dmz device by IP or MAC address.

I have had to do something similar but with a buffalo unit instead of your linksys. I ended up having to place the buffalo unitin into a dmz created on the netopia unit. before VPN tunnles were formed correctly.

VPN passthrough


What are the settings that you have for your netgear router? Its going to tunnel, right? Try this solutions and see it will work.

1. Access the set-up page of the router, from a browser, type 192.168.1.1
2. Go to VPN tab and select IP SEC VPN
3. Local Security Group, set it to subnet and input the Network Address of the router (LAN IP - 192.168.1.0)
4. Remote Security Group, set it to subnet and input the Network Address of the netgear router (LAN IP, for example - 192.168.2.0)
5. Remote Secure Group, set it to IP only, WAN IP address of the netgear router
6. For Key Managemnt, just make sure that all settings are identical with the netgear router
7. Last go to Advanced Settings and make sure that group settings are identical to the netgear router

Hope it works for you

Siements 5890 router


When you say HQ is that outside on the wan port trying to ping the Lan port?
Sometimes the router itself will respond to a ping but will not pass ping requests thru as the internal firewall can never be fully shutoff unless you are running your cisco switch as a DMZ 
also are you connecting your other pc's to the cisco or to the 5890.
Instead of shutting off the firewall completely try enabling bridge mode and give your cisco the outside IP addy.

FAILURE TO CONNECT TO WEB SEVER @ 192.168.1.1


I am assuming for discussion the following connections of the routers. I am also assuming subnet masks of 255.255.255.0 on both networks. The WAN side of the HN7000 conforms to the requirements of the ISP. The HN7000 has it lan side address set to 192.168.0.1 connected between the ISP to the WAN port and the Linksys from a LAN port to the Linksys's WAN Port. What is the WAN side address of the Linksys? -- It should be either be static 192.168.0.? unique and not in the DHCP range of the HN7000 or should be dynamic. If you utilize DHCP it should be enabled for both routers. The LAN side of the linksys router is 192.168.1.1. If the addresses are set up as stated and the routers are either as described or reversed.

Can you access the internet from the HN7000 by wire?

Can you access the internet from the Linksys reliably?

If either of those two are not true assure the DNS servers are established in the routers for DHCP or in the network adapters if that is preferred -- redo the test above and assure access from both networks is possible using wired computers. Attempt to configure the both routers from a computer wired to each router -- attempt to open configuration 2 times on each router and one time each from both wired machine -- record what works and what doesn't.

I would not be surprised in this configuration that the linksys could only be configured from the a device attached to it. But the HN7000 could be configured from a connection to either router.

Test the wireless connections to the internet as appropriate.

When done report any issues in a comment to this problem and I will assist in determining steps to correct issues. OK?
