Hi to All,
I'm moving from isa server to Endian firewall and I need to publish 4 diffresent web server hosted on 4 different machine but I have only one Public  IP address given to me from my provider.
How can I do that?
I know isa server uses host header to do this but i'm not able to find something similar with Endian.
If it's not possible can you please reccomend an open source firewall with this feature.
Thank you
Carlettus

That is a special feature of ISA, as normally what you are suggesting is a reverse proxy or load balancer task, rather than a firewall task (ISA is a strange beast, it is true)

On linux you would normally use the reverse-proxy mode of apache2 (with proxypreservehost turned on) to balance multiple sites using virtual hosting. Normally a hardened firewall specific distro will not have apache, but sometimes it will (for a web based admin tool) so it might be worth checking.  Otherwise you will want to pass 80 and possibly 443 traffic to a second box (running reverse proxy) so as to distribute it out from there.

ISA is an indifferent firewall, but actually a very good proxy (and reverse proxy) indeed :)

Certainly you shouldn't put *anything* else in front of outlook web access, unless you actually want to be a textbook example of "how to configure OWA insecurely" :)
