I am new to ASAs and customer requirements is to have a 5510 connected directly (back-to-back) with two 5505s then traffic from the inside network of 5510 should be allowed to get to the networks behind the 5505s. Returned Traffic initialed from behind the 5510 is allowed through. At no time traffic initialed from behind the 5505s should go through 5510.
5510 is connected to the ethernet0/0 interfaces on the 5505s (by default this interface is the outside interface). I made eth0/0 part of Vlan1 (inside) and the rest of the interfaces part of Vlan2 (outside)
I am able to get into 5510 from the network but not the 5505s also from 5510 I can't even ping eth0/0 interfaces
