So, my network setup looks like this - Code: HFC -> NBN Modem -> Telstra Frontier -> pfsense router -> Switch -> devices I use pfsense as a VPN router primarily as well as running other packages. Generally this setup works without issue however from time to time the Telstra box decides that it will block attempts to connect to the VPN. This normally isn't too much of an issue as I can connect the pfsense box directly into the NBN modem and bypass the Telstra box for a few days until Telstra sorts out whatever the problem is and the VPN starts working through it again. However last time it happened when I was overseas and the wife (rather technically challenged) wasn't happy. I do want to keep using the Telstra box as it has the 4G backup which does come in handy, so I had an idea and tried to set it up like this - Code: HFC -> NBN Modem -> Switch -> Telstra Box -> WAN 1 pfsense -> Switch -> devices |---------------------> WAN 2 pfsense ----| But it looks like the NBN Modem can't handle having more than one device plugged into it. Is there some way of doing this? Or should I just give up and throw the Telstra box away and live without having the 4G backup?
