Title: Need help with port forwarding and multiple static IPs on one interface.
Post by: XOIIO on February 14, 2020, 06:52:37 am
Hi all, so this is incredibly frustrating as my setup had been working, but now it's not and I'm not sure why.

Essentially, I have the ONT provided by my ISP and two external IP addresses available, the desired effect is to have all network traffic default through one, and specific internal IP addresses route through the second.

I have a virtual IP set up for the second address, adding one for the first kills my internet connection. I also have an alias set up for the virtual machine I want on this external IP.

The firewall rules I had set all had been working until last night, however there was an issue with vpn software on the virtual machine host, I had to remove it and reconfigure the network settings, but everything on the host and virtual machine is back to normal, however, I can't get the virtual machine to switch over to the external IP address no matter what I do, and it's driving me insane!

I noticed OPNSense is somewhat slow to apply firewall rules and that's probably not helping much when trying to adjust things, but whatever the solution to this is, I need help figuring it out.

The main IP address I want to use ends in .190 and the one ending in .189 is the one that's for specific use.

I have no one to one or outbound rules since those haven't seemed to fix anything, and they weren't required in the past for this to work.

Is this really such an uncommon use case that nobody has any ideas? Sigh.
