Hi Gabriel,
I'm not sure what you're saying here regarding the use of the second
external NIC. You should not be able to move packets from the internal
network to the external network and not have problems with it (spoof
errors and such).
Are you seeing those problems?
Thanks!

Actually, I have and ISA with 3 NIC, one internal and 2 external.
But with no routing between the external, I`m having the two external
just
to have the protocol and site and content rules work between the
internal
subnet and that subnet. The other extenal NIC is for Internet access.
I hope it helps.

ISA does not support two external interfaces right now. The best you
can do
in this case is to plug the ISA single external NIC into a switch (NOT a
hub) and plug both networks into it as well. Assign both IPs to the
external interface.

Hi to everyone.
I want to setup ISA Server with 3 network cards. One will be connected
to
the internal network, where all client workstations and corporate
file/mail servers are. Two other network cards will be connected to two
independent external networks; each external network has it's own
connection to the Internet (to different ISP). I do have some unix/nt
servers on both external networks - www, SMTP, etc. I want ISA server to
route packets between those two external networks. In the same time I
need
highest level of protection for the internal network.
So, the question: is it possible? anybody has experience with this kind
of
configuration? Do I need to configure specific packet filters to allow
traffic between external networks?
Thank you in advance.
Alex
