I have an ASA5520 with 3 contexts one is the default route for the two others contexts. To interconnect them, I created a VLAN Interface in the system context that is shared with the 3 contexts. I can see the interface in each context. I can ping IP addresses of each interface in this vlan from each context. The default route on the two slaves contexts goes to the IP address of the main context. the return route for the slave context is known from the main context.
I tried to check traffic from slave context to main context I can see in the monitoring that traffic is going to egress interconnected interface of one slave context but I have nothing in the monitoring on the ingress interface of the main context. I checked my security level and traffic allowed on less secure network everything seems to be correct.
On my test, i only tried to install DNS from slave context to DNS forwarder on the main context so I use TELNET "TO IP ADDRESS IN MAIN CONTEXT" 53
