i have an ASA-5510 and there are 4 physical Rj45 ports but when i open ASDM i can only see and configure 3 ports. i already have INTERNAL, EXTERNAL and DMZ configured but i am planning to add 1 more channel for an External network. how can i do this? and is this even possible at all?
what i want is to have my web server and exchange in the DMZ with a dedicated external line and another external line for a faster internet subscription but this will not have a static public IP.
INTERNAL network will access WEB Server and Exchange via the DMZ but all internet access will be through EXTERNAL2 (dynamic IP). all web queries to our web server and exchange shall go through EXTERNAL1 (static IP).
thanks for help in advance.
