Mike, Which interface holds the default gateway? Based on the information you provided, I'd guess the default gateway is on the WAN link. If that's the case, then you'll need at least a single static route to get the ISA server to route traffic over the LAN interface to the 10.4.1.0/24 network. This assumes, of course, that your 10.1.1.29 interface is connected to a router. So, what is the gateway for the 10.1.1.0/24 network? If - for example - the gateway is 10.1.1.1, then you'd want to add a static route to the ISA server using the route command for the 10.4.1.0/24 network. The command would look like below: route add /p 10.4.1.0 mask 255.255.255.0 10.1.1.1 The other thing you'll want to verify is that the 10.4.1.0/24 IP range (10.4.1.0 - 10.4.1.255) is added to the same Network Element that the 10.1.1.0/24 IP range is in ISA. I hope this helps you. :-) Cordially yours, Jerry G. Young II MCSE (4.0/W2K) Atlanta EES Implementation Team Lead HHS Engineering Unisys 11493 Sunset Hills Rd.

But not the 10.4. Do I need to add rules since they are on the same nic? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: gerald.young@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx
