Hello,
I have a strange problem with a site-to-site VPN. I have it completely configured and I have added 3 of my internal networks to be encrypted and access the remote network on the other side of the tunnel.
For some reason, I can access the remote network from only two of the three internal networkls I have specified.
Here is a copy of my config - if someone has any info I would sure appreciate it.
Thanks,
Kevin

can you confirm if we have the exact mirror image of crypto acl on the other end
i feel may be you have a /24 10.239.192.0 255.255.255.0 on the other end as remote network
can you please confirm that
also any particular reason why you are using 10.239.192.0 255.255.255.128 and 10.239.192.128 255.255.255.128 instead of 10.239.192.0 255.255.255.0
09-29-2010 08:46 AM
i see you have vpn filter applied and i assume you are talking abou tthe first tunnel in crypto map
try removing the vpn filter and see what results you get
also what ie the output of packet tracer???
and which is the network which is not accessible
please paste th eoutput of the command
show crypto ipsec sa peer
09-29-2010 09:16 AM
Hello and thanks for the reply.
I have removed the filter and still no luck. Packet Tracer fails on VPN - It says Type-VPN Subtype-encrypt Action - Drop. When I source the packet from an IP from the other two working networks, it goes though just fine.
The two networks that work are 10.239.192.0 /25 and 10.195.64.0 /24. The network that does not work is 10.239.192.128 /25.

Thank You - it was indeed a mismatch of subnet mask that was the problem.
