I don't know. Unless, however, there is a demand for INBOUND traffic which
should be allowed to the remote office (direct inbound TCP traffic, not via
the VPN tunnel). This inbound TCP traffic will be blocked since it's
outgoing ACK pakets will be blocked. Yes, the original poster didn't ask for
such traffic, but (strictly sproken) didn't ask for it to be blocked either
Another way to block outgoing direct traffic to the internet would be to use
utilize the traffic shaper...by defining an appropiate pipe with a packet
loss of 100%.
