Hi @ll,

we have two sites connected with two leased lines. I am now trying to set up an automatic failover with pfsense firewalls on both sites. In case that one line dies the gateways should be switched and the traffic should run over the failover line. Each pfsense should only take all it gets and forward it to the other site.

What i did:
* Configure a gateway group with two tiers on each site
* policy route all traffic comming in at the LAN interface out to the gateway group
* policy route all traffic comming in at the interfaces of the gateway group out to the LAN interface
* tried different scenarios with and without upstream gateways,  with and without configured def gateway and spent some time with static routes and RIP

It seems, that traffic containing retour packets does not get routed through the gatewaygroup (no polcy routing only kernel routing). Without routes, no answer packets are comming back. As soon as i have routes, packites comming back are routed throuth the respective interface.

Has anybody set up similar szenario and can give me a hint?

Thank You
