Question : Monowall to Monowall IPSec VPN

I have setup two monowalls according to the guide located here:

http://doc.m0n0.ch/handbook/ipsec-tunnels.html

The tunnels appear to be up, but I cannot ping across it.

Network A is 192.168.100.0/24 and Network B is 192.168.101.0/24.

Both of these addresses are good: 192.168.100.80 and 192.168.101.80 (they are file servers that will be doing replication); however, I cannot ping one from the other.

Question:

1. How do I know the VPN is actually up and working properly?
2. Where are the logs?

Answer : Monowall to Monowall IPSec VPN

>>  after restarting gets an error  System.ArgumentNullException' occurred in mscorlib.dll

This is because your file is blank and ReadLine() returns nothing, so null is being passed to Long.Parse(). You should consider checking the return of ReadLine() for null before passing to Long.Parse--even if you get the logic working correctly.

>>  it all works except when it tries to write to the file nothing gets written

What kind of app is this? A windows service?

>>  what os are you using

XP
