We have an extrernal Adsl router (it has an Public staic IP), it is plugged into the Wan interface
(220.127.116.11) on the M0n0wall pc, the internal interface is 18.104.22.168. On the Adsl I have a dmz
virtual port, this directs all incoming internet traffic to the Wan interface. I have setup PPTP
server on Monowall and vpn client connections can be successfully established, but once connected I
am unable to connect or ping to anything on the internal network. I created a firewall rule for
interface PPTP that allows all traffic to pass. What am I missing?
