Disabling PF and NAT
There is an old thread that mentions disabling pf will also disable Multi-WAN.. I am assuming this has nothing to do with CARP and redundant firewalls? Just multiple ISP connections?
Thank you in Advance.
Why would the disabling of pf prevent multiple wans? It would prevent the use of firewall rules to make routing decisions is all.
Are you talking about this thread?
There are lots of routers that that have multiple wans. But how traffic flows to these different wans would have to be made via pure routing decision vs a firewall rule.
I agree, it should not matter since I only have one provider and I am wanting to purely route.
pf is required for Multi-WAN the way most people use it – using gateway group and policy routing with gateway groups.
Multi-WAN without pf could still be possible in some cases. Specifically: Default gateway switching or having routing protocol to make the decision of which WAN to use.
