Cable modem problemI have very little testing done with VPN's. My IP rarely 
changes (read as "hasn't yet"), I publish servers thru my dynamic IP with out 
problem. I would therefore assume the same could be done with a vpn, with the 
usual warnings about dynamic IP's and such.

Regards,

  I too have a cable modem with a dynamic IP and have experienced no problems 
with it.  I'm interested though in how I could configure my server as VPN 
server as I have always understood that one had to have a static IP for this to 
work.  Is it possible with a dynamic IP?

    It's very easy to have ISA grab and IP from the cable ISP, I wouldn't 
bother asking for a static IP unless you are prepared to listen to there garble.
    I use ISA to get IP for ISP, then using NAT and DHCP I assign ip's to my 
internal computers as required.
    It's all quite easy and painless.
    I use our script to drop my IP and renew it from my ISP every 24 hours. 
This keeps me and my cable internet idiots happy.

    Let me know if you need any help

      I think. I'm changing from ISDN to a cable modem. The cable co. says I 
must have my ISA server set for DHCP. Followed the instructions in the Learning 
Zone for this type of setup. I tested it against my ISDN router. Set it to do 
DHCP, gave the DHCP Client rule the IP of the ISDN router as the remote 
computer. It won't get an IP from it. I stopped the ISA Control, as suggested, 
still won't get the IP.

      Maybe it is the router, but I thought I would check ahead if anyone has 
any thoughts on what else I might be missing.
