I support a small non-profit which uses a Win XP Pro computer, behind a LinkSys (soon to be D-Link) router, as a VPN server, to allow 2-3 of the officers to connect remotely and update a database. Because we just have a PPoE connection, we don't have a static IP, so we use DynDNS to give us a static hostname, liferingservice.dyndns.org. Our instructions for VPN client setup include telling your firewall that our static hostname is a trusted server.
I'm currently trying to troubleshoot VPN problems from a Vista Home Premium laptop running ZAISS 8.0.298.035; and ZA just blocked me because, apparently, the external IP changed (that's why we use DynDNS, DUH). I have configured my Internet firewall to allow outbound TCP connections to port 1732 - why do I have to add the target IP to the trusted zone ALSO? It's true that I'm the only one using a ZA firewall; but it's a pain to me to have to check the IP all the time. Any suggestions?
Frankly, I would never recommend ZA to anyone without VERY advanced technical skills! God help the innocent newbie trying to cope with this.
