OK, kids; if you can't play nice, we're going to stop and as Bill Cosby
would say "the spankings will now commence!"
Anyone tried this yet?

Hi Steve,
Maybe your cable operator is a great guy, not all cable operators prevent
normal DHCP operations.
HTH,

Hi Guys
Definitely !!NOT!! true, I have been running ISA since beta days, and
installing on customer sites since release. I have a cable modem at my home
install, and am allocated a dynamic IP address, which is renewed every 30
days. I also have or have had many other client installs with dynamic ip
scenarios, and I have had no problems whatsoever with lease renewal at all
whatsoever.

The DHCP filter only works when renewing the SAME IP. Most cable operators
don't acknowledge renewal, until the lease expires, or until the IP is
released. In neither case will the filter pass your request.
MS has fix: Q326116
Another way is to run batch file that stops ISA services, releases and then
renews the IP. Assuming your lease is long enough, you can schedule this
for off hours.
Another benefit of this is that if you release the IP before expiration, you
will get the same IP. I have had published servers for several months on
cable with same IP, and therefore, no need to change publishing rules.

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¨
