I have a site to site tunnel between two 5520 ASAs. Tunnel is up but when I try to talk to the other side, the implicit deny on the inside interface of the local ASA blocks the traffic. When I ping, the tunnel comes up but in the logs it says it is blocking icmp from inside to outside. I have tried the sysopt connection permit-vpn but it is not working. The traffic is from 5 specific machines within the local subnet that I put in a network object group called Celerra_Replication. I want to them to be able to talk to 5 machines on the far end of the tunnel in a seperate subnet. They are in a netwrok object group called GP_Celerra_Replication The ACLs I created for this appear to be created correctly allowing IP from Celerra_replication to GP_Celerra_Replication and the opposite on the other side. Any ideas?
