Actiontec M141WR Port Forward for SBS 2003

We had a tough time getting SBS VPN woking with a Verizon FiOS Actiontec MR414 Router. Some clients can't splurge on a Sonicwall TZ or Cisco Firewall. In this economy we just need to make work with what clients have. No complaning, no belly aching. Working with unfamiliar hardware can cause exessive setup time so its a trade off with clients. Keeping them informed of the issue and documenting the time involved can keep installations from getting out of hand.

We tried connecting to the SBS03 VPN through the Actiontec router. The connectiont just hung at the username and password: Error 800. We knew it was a port issue, but with the Actiontec, you had to open the ports in just the right sequence. At first, we opened all ports as custom. Error 800. Then we created a custom port package with 1723, GRE and 4125 all rolled into one. No go still. We stumbled on the pre-made PPTP (GRE & 1723) in the ports list and then created the custom 4125 and bango, it worked. Now we can shut down 3389 and VPN in.
