Hi I am trying to configure my firewall to allow packets through for a VPN connection. I am running FBSD 5.2 as my router and am trying to connect my laptop from behind the router to our work computer. The laptop is running OSX 10.3.4 with a Nortel Networks client made by Apani. The VPN connection works when the laptop is connected directly to my DSL modem or when behind the gateway when I set the firewall type to 'open'. Support at Apani says that I need to open port 500 and allow protocols 50 and 51 (whatever that means). I found the firewall settings below from the archive and have implemented them before the divert statement (after also) but with no luck. # Allow IPSec clients to run behind firewall # --- ISAKMP - allow key exchange over UDP 500 ${fwcmd} add pass udp from ${inet}:${imask} to any 500 in recv ${iif} ${fwcmd} add pass udp from ${oip} to any 500 out xmit ${oif} ${fwcmd} add pass udp from any 500 to ${inet}:${imask} in recv ${oif} ${fwcmd} add pass udp from any 500 to ${inet}:${imask} out xmit ${iif} # --- ESP - allow protocol 50 (ESP) for everyone ;-) ${fwcmd} add pass esp from any to any Does anyone have a firewall with a working nortel client behind it. I would greatly appreciate any help. Thanks -- Jim Freeze There was a young poet named Dan, Whose poetry never would scan. When told this was so, He said, "Yes, I know.
