Port forwarding to RH 9.0 machine not working


I was wondering if someone could offer some suggestions to an annoying issue I've recently run into. Here's a rundown:

- Using an SMC SOHO router, port forwards to our Windows NT4 server machine work fine. We are running a mail and web server, so ports 25, 110, and 80 are pointing to the internal IP of the NT4 box without issue.

- I have been unable to forward any port whatsoever to the Linux server and am at a loss as to why.

- I can get access to the port of interest from any machine connected to our LAN without incident.

- I thought that port forwarding just redirected the traffic as per the router's specification. Any ideas as to what might be going on? I have tried two different routers and countless firmware upgrades to no avail.

TIA,

JL

Welcome to LQ.

Perhaps there is something funny with your routing table - is the default route pointing to the IP address of the router?

I assume you don't have any firewall rules blocking the port on the redhat box?

Port Forward Woes

Hi there,

Routing table seems to be fine (nothing out of the ordinary in there).

I had tried plugging the machine of interest directly into an available port on the router and even attempted the DMZ option with no luck - seems that I can't forward anything to this RedHat 9.0 machine for some reason but the NT4 server has numerous ports being forwarded without issue...

Regards,

JL
