I am attempting to set up a FreeBSD server as a gateway/ firewall to two independent ISPs for a 192.168.x.x internal network. Here is some of the criteria: 1. Internal network will use ISP1 as primary route to Internet 2. in the event ISP1 fails, ISP2 will be used by internal network 3. In the event ISP1 revives, internal network will use ISP1 again 4. Servers on the internal network need to be able to respond to traffic from both ISP1 and ISP2 (sorry for the ASCII art) ISP1 ISP2 \ / \ / \ / \ / Firewall/ FreeBSD / \ / \ / \ / \ / \ Workstations Servers Is this possible? If so, how? Thank you for your assistance! Eric __________________________________________________ Do You Yahoo!? Yahoo!
