telnet problem / ping ok

Hi Newsgroup!

I have the following setup here at work (see the drawing below) and a problem with the telnet connection to the Cisco 1760 behind the Cisco

2620. I am able to ping the Cisco 1760 (192.168.10.2) from my notebook, but i can't telnet it. When I telnet the Cisco 2620 and then telnet 192.168.10.2 from within the Cisco 2620 i get the login screen. It seems that the telnet 192.168.10.2 isn't "going through" the Cisco 2620... :-(

Tanks in advance! Johannes Timmer

Is your computer using the 2620 as the TCP/IP default gateway? If not, then have you added a route on your computer, to the

192.168.10.0 network?

I manually added a route for teh 192.168.10.0 network on my computer but that didn't work... :-( After I changed the deafault gateway of my computer to 10.5.1.60 (the Cisco 2620) I could establish a telnet connection to the 1760 behind the 2620... How can I get this to work without changing the default gateway?

Cheers

What happens when you remove the access-list from the 192.168.10.2 interface? If you are able to telnet after the ACL is removed, then maybe your ACL is incorrect.

If you are able to initiate a successful telnet to the 1760 from within the 2620, double-check your laptop's IP settings. What are the settings set forth by the DHCP server? Is the default gateway supposed to be 10.5.1.60?
