Hi everyone, this is my first post.

I've read through lots of questions regarding PPTP/VPN functionality 
withing m0n0wall, but I couldn't really find a concrete answer to my 
particular problem.
       1. Remote connections to my external IP, requesting a PPTP 
session fail with Microsoft Windows error 619
       2. Connections on the LAN work just fine (so do connections from 
my wlan)
   
I've setup a NAT Forwarding rule to take traffic to TCP port 1723 (PPTP) 
and send it to one interface address of the m0n0wall (192.168.1.5 in 
this instance). I set up a matching firewall rule to permit traffic 
across that NAT link. After seeing my firewall log (as I have pasted), I 
also tried to forward GRE traffic to see if it would matter. I've also 
run a full-on forward firewall rule: WAN, any port, any protocol, etc 
with no result.

The logs for m0n0 are showing the following entries:
  Firewall:
	13:56:16.160058 	WAN 	Client IP Address
	Server IP Address
	GRE


and the system log shows:

Does anyone have a thought or suggestion that I might try in order to 
fix this issue?

Thanks and best regards,
