I was trying to set multipath route with two default gateways.

I'd like to know just what you did, and, what results were seen, in as much detail as possible. I have to guess that you still had a non-multipathed default route. Ignoring PF entirely, and focusing on your routing environment, I have some questions:
- Did you enable IPv4 multipath routing in sysctl.conf(5)? Confirm it is enabled with $ sysctl net.inet.ip.multipath
- How are you creating the multipath routes? With a !route command in your applicable hostname.if(5) files? With an rc.local(8) script that issues route flush followed by the applicable route add -mpath commands?
- How many default routes are in your routing table? Two? Three? If you have more than two, you have a problem, either caused by a mygate(5) setting or by dhclient(8) configuration accepting a default route, or by not flushing and reloading your routing table correctly.
- Did you watch both interfaces with tcpdump(8) when pinging, or connecting with ssh? I'm guessing that packets coming in to IF2 were still being responded to via IF1.
