Multi-WAN - three connections, one with upstream proxy
We have three WAN connections, two of which allow us directly out on to the internet. The third connection enforces us to use an upstream proxy server.
What I'm wondering is, is there a way in pfsense to configure the third connection to use the upstream proxy and the other two connections not? The hope being I can then chuck them all into a gateway group without worrying or indeed caring about which connection the traffic is going out of.
policy based routing, service based routing or session based routing would be doing the job more or less
better as I see it right.
