Hi, tags with route-to can do, something like that:

# internal interface
if_int1 = "em1"
# external interfaces, first ISP
if_ext1 = "pppoe0"
# second ISP
if_ext2 = "vlan832"
# second ISP gateway
router_isp2 = "2.2.2.2"

# apply tags to incoming traffic for specific ports
pass in log on $if_int1 inet proto tcp from any to any port ssh tag SSH
pass in log on $if_int1 inet proto tcp from any to any port { http,https } tag WEB

# assuming $if_ext1 is default OS route
pass out log on $if_ext1 inet all tagged SSH nat-to ($if_ext1)
pass out log on $if_ext2 inet all tagged WEB nat-to ($if_ext2) route-to ($if_ext2 $router_isp2)

Should work for outgoing traffic. For incoming you would need corresponding "reply-to", although it could get a bit messy with more rules, I find it more simple to have multiple routing tables with rdomain, rtable.

Hello

I’ve had several goes at this but can’t work it out.  Hoping there may be
some assistance available. I cannot find examples I can refine online.

I have two interfaces which I can use for outbound traffic.  One ethernet,
one wifi.  I want to send some traffic out via a given interface depending
on the service I’m connecting to (eg ssh  via ethernet, https via wifi,
etc).
(In the past with linux iproute2 and netfilter this is pretty
straightforward).

Do I need to use route-to or is rdr the tool?

If I only wanted to choose via destination network then simple routing is
sufficient.  Adding a port decision has me stuck.

Or is pf not the tool for this?

Many thanks

r.
