Hello,
I have two internet accesses, and I am using a route-to rule to assign
specific traffic to a specified interface (the way I want in the routing
table).
Various tests have revealed I need to specify the next hop otherwise the
"default" route will always be used.
My problem: I have a really bad ISP which, although I have a static IP,
gives me a different gateway each time the pppoe (using ppp(8) on tun0)
is established.
As this IP changes every time, it is very difficult to hardcode it in
pf.conf
So, I have several solutions so far:
1. change ISP
2. dynamically edit pf.conf
3. ??? magic spell ???
I am sure some PF wizards already have the solution for me... thanks in
advance.

PS: here are my PF rules...
(If stands for interface)
(Gw stands for gateway)
pass out on $ISP1If route-to ($ISP2If $ISP2Gw) from $ISP2If keep state
pass out on $ISP2If route-to ($ISP1If $ISP1Gw) from $ISP1If keep state
PS2: for those who are really interested in details, this is used to
setup two IPSEC tunnels (transport mode) to the same host, making sure
they don't use the same connection - using the Local-address rule in
isakmpd.conf - and I route traffic through them using gif(4) tunnels.
