smoothwall vpn

i work for a small company that is running and windows 2003 small business server that also serves as our vpn server. our firewall is the Smoothwall 2.0 (free version, not that it makes a difference) and we are trying to get it working where it will accept vpn packets and forward them to the server (normally smoothwall only accepts other smoothwall connections, but we want non-smoothwall connections as well)

so we have the instructions on how to set up the smoothwall to work with the vpn, but we get the error
"can't use -A with -A"

we are currently port forwarding port 1723 (gre traffic) to the server...could that be conflicting with the smoothwall vpn fix we are doing?

all ideas, comments, suggestions appreciated

Hi there,

check out the below port assignment table provided by microsoft..


by default TCP port 1723 is assigned for PPTP Routing and Remote Access, my suggestion would be run a port scanner software to make sure there are no other service is using port 1723..

pls post your port forwarding rules on your next post.. will try to validate you rules.. take care..

hi there,

try the below example..

Expand|Select|Wrap|Line Numbers
  1. SOURCE_IP=(your source IP goes here)
  2. SOURCE_PORT=(your source port goes here)
  3. DEST_IP=(your destination IP goes here)
  4. DEST_PORT(your destination port goes here)
  6. /usr/sbin/ipmasqadm portfw -a -P tcp -L $SOURCE_IP $SOURCE_PORT -R $DEST_IP $DEST_PORT
