We recently had to change our ISP router to use VLANs in order to split our public address space into 2 subnets. Now I need to reconfigure the firewall (watchguard x750e) to use the VLAN (65) instead of the external address. I know the firewall has VLAN capabilities, but I do not know how to configure it. Any help or pointers would be most welcome.
original config (ip #'s changed to protect the innocent):
ISP 220.127.116.11 firewall interface (external) 18.104.22.168 gateway 22.214.171.124
ISP vlan65 (126.96.36.199) firewall interface (vlan?) ?.?.?.?
thanks for the help.
