I have two monowalls both running v1.2. I have a ipsec connection set up.
When the tunnel comes up, I can ping the monowall lan ip address on the
remote network, but no hosts on that remote network.

After doing some reading, it would appear that there is a problem with the
local subnet/remote subnet entries on my setup. However, I have double
checked these and don't see a problem.

On side A which has a lan ip address of
10.121.0.254/24<http://10.121.0.254/24>I have the following:
local subnet: lan subnet
remote subnet: 10.0.0.0/24 <http://10.0.0.0/24>

On side B which has a lan ip address of 10.0.0.1/24 <http://10.0.0.1/24> I
have the following:
local subnet: lan subnet
remote subnet: 10.121.0.0 <http://10.121.0.0>

Any idea what I did wrong?

Thanks,
David
