Hi, I hope you can help me or tell me if this is posible. I have an ISA Server as Back Firewall, because theres a Checkpoint connected no the wAN, an the thing is that the Checkpoint accepts VPN connections, and my ISA has 3 NICS (one for intraarray), so I have an interna and an external interface.
I mhave to make to the Cache works (thats the esasiest thing), but when I activate this, the VPNs can get into my internals network. I create a Network Rule fromExternal to Internal as Route, but when I enable this, I cant navigate and cant get VPN clients to interna networks. I cant make a 3-leg configurations because I have no more NICS (besides, communications guys dont want to do the extra work).
So, basically, I want to know if as Back Firewall ISA con route directly External to Internal (Intranet traffic) and Internal to External (Internet, and clients in VPN to Intranet traffic).
I create a Network Rule and an acces rule, and when I do this, I have no conecction to Internet!! I already tried with the Network Rule as Route, as NAT, only with the access rule, only with the network rule, and keep doing the same thing when I do that, and have connection from VPNs and servers at the External interface, Internet access stops....
