NAT/port forwarding issue

[Ancan]

I'm having issues setting up port forwarding so I can access my NAS from the outside. It's a Synology that has a web-interface on ports 5000/5001, and I've opened the firewall like this:

Code: Select all

User defined open / forwarded ports
Source IP    Public port     Private port     Private IP        Protocol	
all          5000:5001       5000             192.168.0.8       tcp

I can see that packets are registered by ipchains on the rule using "iptables -vL FORWARD", but the browser just times out so I guess no packets are coming back.

What am I doing wrong? This shouldn't be that complicated.

You've done this via the Bubba's web interface presumably. Try leaving the private ports field blank.

Cannot do that: "Invalid private port"

Update: Instead of setting "5000:5001" as source port, I made two rules. One for port 5000 and one for port 5001.

Now it works. Hmm

I see. I've never encountered that before because I'm only opening ports on my Bubba, not forwarding to any other machine on my network.

Thanks for sharing, we'll put this on the list. The UI seems inconsistent here.
