Constant Connection Not Failing Over
I've setup a dual-WAN (one cable, one DSL) and it works great for everything except one type of traffic. I have a monitoring agent on each PC behind pfSense, they check in with a remote server every 30 seconds. Think of it like a heartbeat monitor. This type of traffic does not ever seem to fail over on its own. I'm wondering if it's something to do with the frequency that it checks in, so the connections never seem to be new, they're always related… But I don't really know enough about it to make any kind of real educated guess.
I discovered today that if I login to the pfSense and make any kind of a change to the firewall (and then apply the settings), the monitoring connections fail over to the secondary WAN like they should. Does anyone have any suggestions as to how I could make this work better? Perhaps changing the FW to be more aggressive with states could help. I'd be grateful for thoughts on the matter.
I might be pointing you in the wrong direction, but try turning off sticky connections and/or setting Firewall Optimization Options to aggressive.
