Re: VPN through Linksys BEFSX41 VPN - Error 721

Thanks for the help. I hadn't seen/heard of that before, but it got me
lookin. I went back to Linksys site/knowledge base articles and did some
searching.

Ariticle 737 (link to long to post) went like this
"You’ll need to setup Port Forwarding to set up a PPtP tunnel behind a
Linksys router. Please follow these instructions to setup the router to
forwarding incoming PPtP traffic to your PPtP server:"

And instructed to FWD port 47 and 1723 to the server, both TCP and UDP.
Looks like that "port" vs. "protocol" issue does need to be resolved by
opening port 47. Now, the catch was that uPnP setup by windows does open
port 1723, but only TCP and not UDP. (You don't have the option to select
"BOTH" from the uPnP page. You have to manually setup the port fwd on the
port fwd section.

SO, I GOT IT TO CONNECT. And to re-iterate, i didn't have to down grade my
firmware either.

Now, working out some more details to come (it doesn't seem to be acting
right on my systems... ) i'll put that in another thread.

THANKS EVERYONE!
