i recently involved in one of the ASA 5520 firewall installation. We ordered the 2 firewall with limited 4 ports to support the client's exsiting 7 Networks.Now we have found the port shortage to support the said number of the interfaces (7). I configured the firewall in LAN fialover usign 1 ports exach from the bothe firewall. Now we have 3 ports in eaxh firewall to support 7 networks (I Internal ,1 Outside, 5 DMZs).
Please could u give the solution to configured the sub interfaces to solve the issue. Client already bought the AIP-SSM for the slot in free.
Thanks in Advance.
