You really can't get another NIC?

Oh- I didn't get that.  You want to filter all traffic through the ISA
by port forwarding through the NetGear just to the ISA box even though
the other boxes are on the same segment with a single NIC?  Get another
NIC dude!

Whattayadoin? Spending all your money on beer?

Harder rule based and app filtering of inbound crap :) as you know, you
cant filter by ip with that linksys. Maybe until the sveasoft firmware
comes into play.

Sure, it'll work... But what is the ISA server there for?  You got a 3rd
leg there?  (Remember, *family list*)

Hi guys

Need some brain help on a Sunday night. The situation im dealing with is
this and I want to know if it is possible.

Router at the edge. Port forwarding to the isa machine (single nic, same
internal ip range as the router and the clients) gateway of the isa is
the routers internal ip. However I would like to know if I can use the
routers internal ip as the gateway for the snat clients, thereby
bypassing the isa for outbound traffic.

I know I really could use the isa to filter my outbound stuff but I want
to know if this will work in a single nic environment. Or will I have
problems with the internal and external network sets on the isa 2004
machine.

Router:
External: 210.27.98.12
Internal ip : 192.168.100.1

ISA:
Internal: 192.168.100.2
Gateway: 192.168.100.1

Clients: 192.168.100.3-254
Gateway: 192.168.100.1


I hope that makes sense. I cant think anymore!

Thanks

Greg
