Internet based games (otherwise known as on-line games) by design are the
exact opposite of what a firewall is.
On-line games basically require you to "open" a range of ports to the whole
world.
On-line games and security are mutually exclusive.

http://www.ISAserver.org
Hi Experts
Firstly let me say I am new to ISA server, so please exscuse me if the
answers are obvious.
I have setup a ISA2004 server in my home testlab. I have a ADSL Router\FW
which NATs from my external IP to a 10.x.x.x address range, this is inturn
connected to the External interface of the ISA server which then NATS to a
192.168.x.x range. obviously the internal 192 subnet is connected to an
internal Interface on the ISA server which is also the default gateway.
I used the Edge firewall template I have setup initially rules to allow all
outbound traffic. I have published SSH, SMTP and OWA servers internally
which is working fine (OWA has a few probs with authentication with ssl
though , not using forms based)
I have a few internet based games (driven by gamespy) and I cannot see a way
of setting up an equivelent to Nat open port redirection so that return
external traffic knows which host to be redirected too. I tried server
publishing but that open the ports for external access, which is not what I
want,
Is there any articles or walk throughs on how to setup gaming on isa2004
server? I thought it might be the FW client config but I have not found any
examples of this.
