Telnet issue

[John Blakley]

Ok,

I posted a couple of days ago about a telnet problem that I had where I could ping the router, but couldn't telnet to it. There are NO acls involved at all.

Well today, I figured out that I can telnet to the router from another router, but not from a host behind the router. It looks like this:

Cannot telnet: host -> router -> router

Can telnet: router -> router

This doesn't make any sense to me at all. Any ideas?

You need to format your ACL for the interesting traffic from the source to destination and vice-versa.

To make things simple, try a source w/ the problem that is closest to the destination. Initiate the test and see what the debug displays.

Another suggestion will be, if you have a lab, try dumping the configuration from the routers into the lab and see if you can duplicate it there.

I'll have to test it out in a lab. I want to see what I'll have to look for, and I HOPE I can recreate this in a lab. :-)

I'll let you know tomorrow what the results were!

Thank you!

Okay, I set up the lab exactly as it is here, and I couldn't duplicate the problem. I give up, and I'm just going to telnet from the box that I know can get to it. It's just a really weird situation that I can ping from both directions, but not telnet. Odd.

Usually, when I see issues with no reasoning behind it, a reboot usually fixes it :)

Give it a shot.

i fully agree with edison for checking the route in the target router to host network belongs and check for the default gateway of the host.
