Trying to set up a S2S to a Checkpoint box with BM3.8 (SP everything :).
BM is already doing S2S for a couple of non-BM S2S VPNs, as well as
40-odd clients.

However, I'm getting no traffic crossing the tunnel. The last thing in
the logs relevant to this site is:

ESP-SA is created:algorID=esp
3des,mySPI=22DF7CBE,peerSPI=94CAA290,time=73430 ,

There's no errors (or anything relevant) after that.

However, the NRM VPN activity screen shows the IP connection as the
little-bouncing-dot graphic, and the connection state is listed as
"pending". Consequently, nothing is crossing the link.

Any clues?
