I have 2 blocks of IP Addresses, on on a /29 and another on a /27. I am using an Adtran Total Access 612 router that connects to my Watchguard Firewall. The /29 network is currently connected to my Watchguard’s external interface. I will be configuring an additional interface on the Watchguard for the additional block of IP address I received from T1 provider. How to I route the additional block of IP Addresses to an additional external interface to my watchguard with only on network card on the Adtran Total Access 612? Is it as simple as connecting a patch cable from the Adtran to a switch then patch cables from a switch to the external interfaces on my Watchguard firewall?
