I have a 5505 connected to 5510 via a site to site VPN, the vpn has 5 subnets on the acl list at both ends, but 2 of the subnets are assigned for remote access on the main 5510, which means the flow of traffic on these 2 subnets are main to remote, but the VPN only works if the traffic starts from remote to main.
both sides are set to bidirectional and I'm not sure if this is the case for all 5 subnets has remote site always sends data to the other 3 subnets first.
