I have 2x 1941's in my home lab with one client on each router. no net connection. I can ping from 1.10 to 2.10 but not the other way around. Any ideas? this is driving me nuts. I can ping all the way to gi0/1 through both s0/1's
R1 has a W10 client on it 192.168.1.10 255.255.255.0
R2 has a Pi on it 192.168.2.10 255.255.255.0

from your 2.10 test the following:
see if you can ping the 2.1
see if you can ping then serial interface of the router
see if you can ping the serial interface of the remote router
see if you can ping the 1.1 on the remote router,
see what works and what doesnt and isolate the problem by braking the path up
please rate if useful
04-05-2017 08:56 PM
forgot to include that...I'm exhausted. yes, I can ping 2.1,3.2,3.1,1.1. so everything but the client
04-05-2017 09:31 PM
can you ping 2,10 from 2.1
and 2.10 sourced from 3.2?
04-06-2017 01:41 AM
yes, everything pings except 2.10 to 1.10
04-06-2017 02:14 AM
Can you ping 1.10 from Router 2 using the source of 2.1 ?
04-06-2017 06:57 PM
yes.

Hello
Turn off any software firewall on the windows clients or allow them to receive echo-reply

tried that. I can ping from r1 to the 1.10 client but not from client2.10 to client 1.10
04-06-2017 06:59 PM
I just swapped IPs of the clients and swapped their ports...same thing. I really doubt its a firewall issue.
04-07-2017 08:26 AM
So when you swapped IPs could you then ping from 1.10 to 2.10 or not.

04-07-2017 06:45 PM
Yes...exact same problem as before.
04-10-2017 04:42 AM
still unsolved...should I post this somewhere else?
04-10-2017 06:38 AM
Hello
As you are specifiying static routes towards an interface instead of next hop then you'll need proxy arp enabled on each interface your statics point to
so try enabling proxy arp

Thanks for the reply. I set ip proxy-arp on every interface...same issue
