[pptp-server] pptp portforwarding

[Heusden, Folkert van]

Hi,

On our intranet, we're running an NT-server capable of ding pptp.
I've been trying to get pptp working on the linux-box, but couldn't
get it to work, so I decided to have the router (linux) forward it's
incoming pptp-connections to the nt-box, as it does with smtp and
pop3-sessions. Should do, shouldn't it?
Ok, I got these firewall-rules:
PPTP forwarding:
/sbin/ipchains -I input -p tcp -y -d __INTERNET_IP_ADDRESS__/32 1723 -m 1
/usr/sbin/ipmasqadm mfw -A -m 1 -r __IP_ADDRESS_FOR_THE_NT_BOX__ 1723 -p 10
/sbin/ipchains -I input -p 47 -d __INTERNET_IP_ADDRESS__/32 -m 2
/usr/sbin/ipmasqadm mfw -A -m 2 -r __IP_ADDRESS_FOR_THE_NT_BOX__ -p 10
but that doesn't seem to work.
Anyone got any suggestions?
