Hi Glen, EXACTLY. ISA Server really was designed to be a true firewall, with strong inbound and outbound access control, not a SOHO NAT server :-) Thanks!

I don't know of a scenario whereby ISA SERVER can be programmed to change automatically.. You will have to change PACKET FILTERS, and published servers when this occurs..

I have a problem with my ISA server. I seem to loose the external ip adress, wich is assigned by DHCP. If i stop all ISA services I receive an adress just fine, but when ISA server is Activated I can`´connect to my ISP:s dhcp. What have I missed?
