I really did it this time. I was having trouble with the company router
so I put up a m0n0wall. I have been running two for some time without
I tried fixing it today (Sunday) and I've already had 6 phone calls
about VPN being down. Now it's 10:30 Sunday night and I can't figure
out how to fix this before Monday morning. When I try to connect with
VPN it is giving me a 721 error. PPTP won't connect.
Here is the situation: I have PPTP redirected from WAN to
192.168.1.202, which is a windows 2000 server. I know the server works
because it worked with the other router and it works inside the
That didn't work so I added firewall rules allowing ports 1723 TCP and
GRE protocol to 192.168.1.202. No go.
Then I tried adding a rule to allow TCP/UDP port 47 to 192.168.1.202,
and that didn't work either.
The previous router was set up this way: 1723 > 192.168.1.202 port 1723
and TCP/UDP 47 > 192.168.1.202 port 0 on that router indicating "all
ports" and it worked perfectly FOR YEARS.
So I tried to replicate these settings in the NAT table on m0n0wall.
Port 1723 was a no-brainer to redirect, but 47 I can't enter the way it
is supposed to be. I enter TCP/UDP 47 but it won't let me re-direct it
to a range of ports, just one.
I have no idea what to do, and I'm freaking out.
