Hi Everyone,
I wanted to find out if anyone has run into this before. I can't find it 
anywhere in the mailing list.

Basically, we have (2) sites that have m0n0wall.  Each is using the 
built in PPTP which works great. Both use m0n0wall as a NAT/Firewall/VPN 
setup. The odd thing is, should one person from Company A do a VPN into 
Company B, it works.  But, if Company B does a VPN into Company A while 
Company A is still VPN into Company B, they both cancel each other out 
and you have to restart m0n0wall at both locations to fix the problem. 
Just to clarify, I'm not going VPN from m0n0wall to m0n0wall, but it's a 
computer behind the NAT doing a VPN across to each other that causes 
this to happen.  Now, I think maybe there is a good reason for this, but 
I don't know what it is, LOL.  Any info would be greatly appreciated.

Thanks,
Michael
