I have tried everything to get Port Forwarding to work. I even factory reset it with no new results.

I had a weird error in logs at first: iptables v1.4.21: invalid port/service \--to-destination' specified`

I factory reset, that error is gone, but it's still not working. I can't change my firmware because I have a firmware that shows a different number so it thinks i'm trying to downgrade.

I've disabled all firewall settings, talked to my ISP about Double Nat and got that fixed, still nothing. I cannot perform a firmware upgrade no matter how hard I try, it always fails. I've set the rule up as follows:

SERVICE TYPE: CUSTOM

SERVICE NAME: SSH SERVER

INTERNAL IP: 192.168.68.105

INTERNAL PORT: 22

EXTERNAL IP: (BLANK)

EXTERNAL PORT: 22

PROTOCOL: TCP

Port still shows closed, cannot use SSH to access.

Can access locally on the same network no problem (server is listening)

I've reserved an address from my server.
i've check my public IP to make sure I wasn't on Double NAT. I'm not.

I've attempted a firmware upgrade, fails every time.

The logs show that the rules were set without error...

I'm at a loss.
