ZyWall VPN2S Port forwarding not working.
Options
Dear All,
Port forwarding not working on my recently installed device VPN2S.
Setup was processed as is written in User's guide.
Device is with latest firmware version (1.20(ABLN.2)C0)
Any ideas how to proceed?
Thanks in advance.

Have you setup a firewall rule?
Is the forwarding IP correct?
what port are you trying to forward TCP/UDP?0 -
Hello PeterUK,At the moment Firewall is disabled.I am trying to forward TCP port 6999 to internal machine on port 70000

Is the VPN2S getting the WAN IP and you are not double NATing?
Is forward rule enabled?
Is WAN interface set to the right WAN?
Your ISP could be blocking this port?
Go to maintenance > Diagnostic > packet capture put in a file name and filter host port portrange 6999 - 7000
start capture
go to GRC and scan for port 6999
GRC | ShieldsUP! — Internet Vulnerability Profiling
click stop capture see if you port shows up.0 -
Hello PeterUK,Yes, VPN2S is getting the right IP.Forward rule is enabled and firewall exception is added.This port is not blocked by ISP because forwarding works with my old router.Firewall is disabled during the tests for port forwarding.

With port listener I can get the port to show open here you need firewall rule port 7000 but as you have the firewall off it should work.
Having port mapping from WAN to LAN be different does not add security so try 6999 to 6999 or 7000 to 7000.
