Title: Port forwarding for internal web server
Post by: Hemeltje on February 05, 2005, 09:03:26 AM

I have a web server listening to port 8040 behind SME.
The web server works ok when I use a simple hardware router (D-Link, SMC, USR, all work ok).
But not with the sme server!?
In the server-manager I created a port forwarding rule that redirects all TCP/UDP to webserver:8040. :cry:

What's going wrong?

Should work fine - are you using the portforward contrib? You can easily check the firewall rules with the masq-manager contrib. I guess you are sure you have the correct ip for the webserver :)

Is a portforward contrib needed for 6.0.1-01?

Hi - what I mean is did you do the portforward from the server-manager or try to write a firewall rule?

Yep!
TCP - 8040 - 192.168.0.12 - 8040

I guess I do better a complete new install and try again on a clean server.

Peter,
It is port 80 you are forwarding to the webserver listening on 8040?

The router is listening on port 8040 and forwarding to the same port 8040 on the webserver (192.168.0.12).
This works with USR router.
Now I try this with SME server but I get:

...
The following error was encountered:

Connection Failed
The system returned:

    (111) Connection refused
...

Any idea?

Peter

If you throw on Muzo's firewall management contrib you could check the rule has been created - it should show up under NAT Chain PortFowarding. You can also list the rules at a command prompt with iptables -L and use Shift Pageup & Down to scroll.Otherwise I'm out of ideas.

I found this:

Chain PortForwarding_1404 (1 references)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp dpt:8040 to:192.168.0.12:8040

So it should work, I suppose? But it doesn't! (and internal - http://192.168.0.12:8040 works fine)

I'm out of ideas...
