20.7 Legacy Series / Can I port forward to an external/public IP?

« on: August 16, 2020, 05:32:41 pm »

Hello.

I'm trying to do a port forward of incoming traffic through a certain port to an external IP. However when I implement the rule, traffic is not passing, even when I put an allow all rule.

It's working perfectly when I put in a LAN IP to forward to. But when I put in the public IP on the cloud, it's not working.

Incoming public traffic => firewall port 22000 => 192.168.44.44 port 22 (working fine)
Incoming public traffic => firewall port 22000 => 44.44.44.44 port 22 (not working)

I tried reaching the IP and port from inside the firewall, and they are successfully reached. I can even SSH  to the IP from our network and from the firewall. But when I try to port forward from incoming traffic to the server, I get a timeout. Any reason why this is happening?

General Discussion / NAT/Incoming traffic not working when going to secondary gateway/IP

« on: February 25, 2020, 11:02:41 pm »

Hello all.

We've just installed 2 additional internet connections. We've created a total of 3 VLans, 1 for each WAN, and we've setup the gateways for them.
Outgoing traffic is working great.
Incoming traffic that needs to be natted however, only works on the main gateway IP/interface.
Example:
50.50.50.1 (main gateway)
50.50.51.1 (second gateway)
50.50.52.1 (third gateway)

When I call ip 50.50.50.1 port 443, traffic reaches our web server (Located on LAN) and it responds back normally.
However, when we call 50.50.51.1 or 50.50.52.1 port 443, the web server is unable to reply, and the requests timeout.

If we switch the main gateway, for example make 50.50.51.1 the main gateway, then traffic to it's interface works, and traffic to the other 2 stops.

Any idea why this is happening? Am I missing a configuration?
