Hello fellow forum members,
Since I'm still quite new to OPNsense, I'm looking for some advice here.
I installed OPNsense (version 14) on a Sophos XG310 because I felt it was a waste to return it to the manufacturer (support is ending soon). Every now and then, one of the twelve network interfaces goes missing. I can't quite explain why that happens.
I've configured a connection to Plusnet via a DSL modem. Upon dialing in, I am assigned an IP address. Once the connection is established, a transparently passed-through IP network with public IP addresses (217.xxx.xxx.xxx) becomes available, which I would like to route to the DMZ interface. How do I do that? Bridging?
In addition to the Plusnet DSL connection, there is a connection to Stadtwerke Schwedt (OPAL/FTTH). If the Stadtwerke Schwedt line is unavailable, internet traffic should be routed via the Plusnet DSL connection. Both the OPAL and DSL connections should remain active at all times, whereas the third connection—via LTE—should be configured solely as a backup.
It's probably not easy to say exactly how I should proceed, and there are likely various ways to handle this.
However, I would really appreciate any suggestions for a solution.
