Re: Error 721

Many thnanks to the two Franks & Leythos for responding.

Does the pptp test the GRE 47?

Also, something Leythos said has struck a chord......

I haven't tried to establish a VPN from a remote client for a long time, but I don't remember having any previous problems. Did the tech guy ever find out if SP3 was the problem?

I doubt the other Frank's answer is your problem since you are talking VPN
and he is answering RWW. Error 721 is always GRE 47 error

Yep, I agree, seen it time and time again.

Just had a tech that supports a medical system try and get access after
installing SP3 on his system last month (this was his first attempt
since SP3) and he could not get into the firewal - a PPTP Appliance.

All other users on that network without SP3 can get into the firewall.

Most times this was caused by cheap/bad router firmware on what people
mistakenly call a Firewall, which is really a NAT Router.
