There's no such thing as "default gateway for a subnet". One way to do what you want is with PF "route-to" rules applying only to packets with a source address in the subnet of interest (and likewise for "reply-to" to handle incoming connections, maybe in conjunction with rdr-to). This is a little messier config, but if the old setup will be going away after not too long, it might be easier to handle. Another way is to use multiple route tables (put the relevant interfaces in a different rdomain, e.g. "rdomain 2" in the hostname.if files), and use "-T 2" when adding routes relating to that), this is cleaner/simpler in some ways, though it can also be more tricky if you're running any services on the router itself (you may need to run a second instance bound to the second rdomain). > https://misc.openbsd.narkive.com/lCGUlP2Q/two-default-route > > I think the above was more to do with using 2x default routes in a > multipath setup rather then simply trying to get one particular subnet > to use another ISP specifically. multipath is not what you're looking for here > Also one last note: I'm not using the /etc/mygate at all.... it was my > understanding that when building a router you didn't need it and > certainly for now I have never needed it with the VSDL2 link from ISP-A. that's ok, your default route is over pppoe which you can't do via /etc/mygate.
