Having a bit of fun with Setting up Policy based routing.
I have 2 ISP’s and I want certain computers to get routed over the 2nd ISP.
ISP1 Is a static IP connection on ETH1 provided by A bridged DSL modem, this is my system default router
ISP2 is PPPoE from a bridged DSL modem on ETH2.
Whilst the ISP2 provided IP is static the default gateway IP can change on Reconnect meaning a static route tends to be useless.
If I set the option to automatically add a default route on PPP connect that of course adds the correct route for the session however the problem then is that it overrides my main route, I really only want this route to be used by certian machines (PBR) and maybe as a backup if the primary connection dies.
I did think of having ISP2 as the default and then Tagging everything that’s NOT on an address list for ISP1 but I seem to manage to break my NAT translation on ISP1 when i do this.
