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!
Tom

It is HIGHLY recommended (per Shinder book p. 208-212) that your external
interface have static addressing.. 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..

Hi!
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?

Regards/

Jimmy¨
