Strange Issue with IPsec tunnel

Hi everyone!

I have 2 Soekris Monowalls connected with Ipsec and I have been having some
issues since early this week.

Location 1 (L1 ­ our main office) can ping/connect to Location 2 (L2 ­ our
Colo) with no issues at all. Everything works just fine. But L2 cannot ping
anything at L1. When I do a trace route from L2, it stops at L2¹s firewall.
If I use PPTP to connect from L2 to L1, all works perfectly.

I did make some changes to L1¹s firewall (added a DMZ) but I don¹t remember
changing any of the rules. I would have to assume that I did something to
the L1 firewall to make this stop. I just can¹t figure out what. Anyone have
any thoughts on this? I can send screenshots of the rules on L1 if needed.

Thanks
