VPN

here is my setup.

I work in an office that I have a m0n0 setup here that is accepting VPN connections.  T1 is the connection.

I have a m0n0 setup at home on my cable internet as well that is accepting vpn also.

When I am recieving DHCP from my office m0n0 I cannot connect to the VPN at home. 

If I set a static IP to route directly through my T1 router, I can get on the VPN at home with no issues.

Any suggestions?

Are you already connected with another machine through the m0n0wall? You can only connect to a single PPTP server once because of GRE NAT limitations, trying to connect a second time will cause a 619 error.

CMB statement is true, the limitations of GRE on a Single public IP will only allow one connection. Also error 619 is a port disconnect. It is possible that it's a routing issue. When you set a static did you set the default gateway to the firewall LAN interface or to some other DNS server. Also are there any other device on the network that might have DHCP enabled that your not aware of.
