[isalist] Re: Two ISP's one NIC

Won't work. You'll need a dual WAN router in front of the ISA Firewall.

        Subject: [isalist] Two ISP's one NIC
        
        
        I am running an ISA 2004 appliance.  I want to bring in a second
Internet connection to supplement my primary.  My goal is to have
traffic that uses our public IP addresses (remote access, web
publishing, incoming email) use the primary and web browsing use the
secondary.  Here is my plan please poke holes in it. 
         
        Connect both ISP connections to a switch.  Connect switch to the
WAN NIC on the firewall.  Configure the WAN NIC with IP addresses from
both ISP's making the secondary ISP the default gateway.  
         
        I don't care about load balancing.
         
        If this will not work what are my alternatives.  This is short
term until my primary ISP can bring fiber into the building.
