You can work around this issue in one of two ways:

1) You should find a checkbox in the properties for the PPTP DUN connection 
on the client for 'Use default gateway on remote network' (or something 
similar). If you untick this, only traffic destined for the remote VPN 
subnet will go over the PPTP VPN. If there are additional subnets behind the 
VPN you may have problems accessing those unless you add some static routes 
on the clients.

2) Create NAT and firewall rules that allow the PPTP clients access to the 
Internet on the PPTP server. You may need to switch to manual NAT rules to 
do this. I have tested this myself and it does work.

I don't think it is a m0n0wall issue, but a Windows issue. Windows
assumes that EVERYTHING is supposed to go over the PPTP connection. I
have had this happen, forget that this is normal, and think there is a
problem with my internet connection. It is not. As soon as I disconnect
the PPTP, everything is normal...

Unless someone has a solution, I think that this is normal operation...
