Hi there, I have found that when I put multiple addresses on an alias interface, the port forwarding stops working. It has been the case through multiple iterations of nethsecurity. I am on 8.4 now and it is still doing the same. If I remove the additional addresses, the forwarding works correctly. Currently, I have 1 address on the logical wan interface and then I am trying to put 3 on the alias interface.
Yes, I have set the wan address there. I am also noticing that source nat is not working to get email going out the correct wan address. I did have all this working on a machine with 4 nics in it so I didn’t have to add all the aliases, but the RAM has failed on that machine, so I’m currently having to do it with just a single physical wan interface. Also, I’ve configured logging on these forward rules, but I don’t see anything in the logs.
Also, now that I have moved it to the new machine, even with just one alias address, the port forwarding won’t work on the alias interface. It does work on the main interface. Using tcpdump, I can see the traffic getting to the computer, but I do not see it in the logs for the port forward. So, I don’t know where it is being rejected.
