Error 721 means the GRE traffic is blocked. If you are connecting using
PPTP, then you need to allow IP protocol 47 (note that this is not a port)
on the router/firewall in the middle.
If you are connecting using L2TP, then you need to open up ports UDP 1701,
UDP 500 and UDP 4500.

I have a Windows Server 2003 SP1 box set up with Routing and Remote Access
configured. When I leave this server sit in the DMZ, I have no problems
getting VPN clients to connect. When I take this server out of the DMZ
and
open TCP 1723 and UDP 500 on the router only, no VPN clients can connect
any
more. It sits at ...Verifying username and password... and then after the
timeout messages Error 721: The remote computer did not respond.
Am I missing a port here that I need to open on the router? I'm assuming
I'm missing something to be opened on the router yet I don't know what it
is.
Any help would be greatly taken.
Thanks in advance.
