Cisco 4000/25001 Routers able to ping in only one direction 1

[ad73]

Hello:

I have two locations using Cisco Routers connected to Adtran ISU's connected via ISDN.

At Location A (MAIN SERVER SCO UNIX 5.0.6), I have a Cisco 4000 Router (connected to Adtran ISU's), and at Location 2 (REMOTE) I have a Cisco 2501 Router (also connected to Adtran ISU's.

Here is my problem...

When I am at the remote location - I can ping any IP device at that location (router, Micro Annex XL), AND I can ping Accross the ISDN line to the MAIN SERVER LOCATION, and ping any ip addressed equipment on that side ( Servers, Computers, printers, etc). But from the MAIN SERVER LOCATION, I can only ping the Router at the REMOTE location. Any equipment "behind" the router, at the remote site (Laptop, Micro Annex XL) cannot be "ping"ed from the Main Location.

Since this is the case I cannot get my server - at the MAIN LOCATION to COMMUNICATE with WYSE 60 dumb terminals at the REMOTE SITE through the Micro Annex.

By the way I can also VPN (using my Laptop) from the Remote site to a CITRIX METAFRAME SERVER at the MAIN LOCATION - but oddly enough even the CITRIX server cannot "ping" the laptop across the routers?

Is there a Cisco Setting in either of the Cisco Routers that could be responsible or is there something else going on here? Ny suggestions would be appreciated?

Regards

Sounds like inside the main LAN, pings are blocked. Post a config of that router---no question that everything has routes, because ping replies are being sent (two way routing is all good).

Thanks burtsbees:

Here are the Router Configurations for BOTH the ROUTERS ( I think this is what you needed - but please let me know if I should post any other information.

[Alterac]

Main site router
Serial3

your missing:
dialer-group 8

 

[ad73]

Added the dialer-group 8 to serial interface 3 at main site router. Saved to memory. Cycled up and down and no change.

Any other thoughts ?

 

[Alterac]

try enabling on main cisco.

service udp-small-servers
service tcp-small-servers

[Alterac]

Can probally ignore that small-servers post

Do the devices at the remote office have a default gateway set?

router rip
network 192.1.0.0
RIP cannot route classless or summarize.
Try either using version 2 and auto-summary or advertize all subnets.
Why are you using public IP addresses on the LAN? Do you own 192.1.0.0/16?
