Port Forwarding Problem on AC68U

[WRobertE]

I'm running 386.1_2 on an RT-AC68U and I'm unable to get port forwarding to work. It used to work but I don't know when it stopped working.

Basically I have remote cameras in my mother's house and I'm forwarding recorded video to an FTP server running on my Synology NAS.

I've setup this port forwarding rule on my router:

On the router, when I run the command:

iptables --list-rules

I don't see any rule that references this information. So, it seems like something with port forwarding is broken.

The remote cameras can login to the Synology NAS but they can't forward anything to the FTP server on the NAS. I've checked all permissions on the NAS for the account used by the cameras and all that is correct.

This isn't my area of expertise ... what am I missing? This is driving me nuts!

Use

iptables --line -t nat -nvL VSERVER

OK ... I see the rule now. Thank you.

But I'm still stumped as to why it's no longer working.

Here's my setup on the Synology:

FINALLY figured it out. Turns out to be a setting on the Synology. Appears to be a new setting that I didn't have to use before.

Thanks again for the help.
