I am positive that this exact same setup has worked in the past with previous versions of the firmware (maybe 121 on the Linksys E4200v1 but could be other. which makes me conclude that the return traffic is "blocked" probably (?) by a missing rule.Īs this is a very common scenario I am sure other people must be experiencing this issue as well. However I cannot see anything on the outgoing / return packet side. Through connection logging of the Firewall, I can clearly see the incoming packets being accepted and going through the iptables rules. The connection status for that case shows: However doing the same from the internet does not work and eventually results in the connection request timing out. Note the public IP as the destination for the ssh connection (!) Port forwarding is working correctly (!) while I test it from the inside/private network to the public external IP address (!!).īelow you can see the established connection. For the setup I am using a "static public internet" address at the external port (vlan2) and a "static private IP" address for the internal server." "Redirect ssh traffic from the internet to an internal server. Unfortunately because of my limited knowledge of iptables I have not been able to find a workaround. The port forwarding issue is present in both versions (!), however this time I dedicate some time to troubleshoot as I really need this to work.Īfter some analysis I came to the conclusion that the issue lies with iptables, and any solution should also be viable through changes in iptables. I have recently upgraded from a Linksys E4200 v1 with shibby version 124-EN to to Asus RT-AC68U (aka T-Mobile AC1900) with shibby version K26RT-AC-131-EN.
