What is the preferred placement for a OWA front-end server given these two possible network configurations and why? 1) [Internet] <==> [PIX Firewall] <==> [ISA Proxy] <==> [PIX Firewall] <==> [OWA] <==> [Internal Net w/Exchange Svr] 2) [Internet] <==> [PIX Firewall] <==> [ISA Proxy] <==> [OWA] <==> [PIX Firewall] <==> [Internal Net w/Exchange Svr] Notes: The ISA server is performing a reverse proxy for HTTPS connections. In #1, the backend firewall will only allow port 443 through to OWA. In #2, all ports required for OWA to communicate with the internal exchange server is allowed.
What type of clients? Road warrior employees with laptops? If so, how about: 3) Verified client with proprietary VPN client and AES 256 -> Big bad Innernat -> Firewall only allowing connections from proprietary VPN client -> ISA Proxy -> OWA & Exchange ...D _______________________________________________ firewall-wizards mailing list firewall-wizards () honor icsalabs com http://honor.icsalabs.com/mailman/listinfo/firewall-wizards
