Title: Port forwarded packets being dropped - why? Post by: bitmonkey on Monday 22 June 2009, 11:56:07 pm I have set up a port forward as follows:
Protocol: TCP Incoming IP: <ANY> Port on incoming: 3333 Destination IP: 192.168.1.2 Destination port: 3333 Enabled: Ticked Source, IP or network: Left blank I have applied the rule and it shows up in the list of port forward rules OK, but traffic is still being blocked with firewall log entries like: INPUT:DROP ppp0 KEY_TCP <SOURCE-IP> 1992 ::::: <MY-EXTERNAL-IP> 3333 Do I need to edit something else? Have I set up the port forward rule incorrectly? nb. the box 192.168.1.2 (the destination for the port forward) is not on the LAN of endian (which is a DMZ) but behind another firewall attached to that DMZ, all routes are correct, traffic is OK for everything else and the relevant ports are open on the internal firewall (not that that would change anything if endian is dropping the incoming packets before they get to the second firewall anyway) - just thought I'd mention it, but don't think it will be relevant. thanks Title: Re: Port forwarded packets being dropped - why?
