Just tried again, and this time, both inbound/outbound GRE works.
I also made sure that my RRAS Server is inside of RAS and IAS Servers
group.

Still getting Error 721 on client side and the following on the server
side... I can see that the port on the server side changes it's
condition from Listening to Authenticating then after timed out, get
back to Listening again...

Event Type: Warning
Event Source: RemoteAccess
Event Category: None
Event ID: 20049
Date: 1/7/2005
Time: 3:59:21 PM
User: N/A
Computer: SERVER
Description:
The user connected to port VPN3-16 has been disconnected because the
authentication process did not complete within the required amount of
time.

Really have no idea where it went wrong...

Does anyone has any suggestions on how to fix or how to troubleshoot
this?

Thanks

Charlie Chang
