S360 routing issue

chadcarter_ironport · ‎12-10-2009

I recently installed an Ironport S360 box. Using only the M1 interface in proxy forward mode. I have an issue with routing. I have defined routes on the box for networks in different subnets but the Ironport is not able to route traffic to these networks. Everything works fine with traffic from the same subnet or if I have it pointing to a core network switch with those routes. Is there any reason the M1 interface would not adhere to the defined routing list?

Well, I can only think of a couple of possible things you could check. Do you have the slash notation mask added to the end of your route statements? It should be entered as "Route Name" "Destination Network" and then "Gateway", for example: "Route to NetworkA" "192.168.1.0/24" "192.168.2.1".

If this is not the case, do you have the "Restrict M1 port to appliance management services only" check mark selected under your Interfaces section?

Hope that helps.
