You can use tagging for that with prob rules and then use route-to on tags.
Since PF will use route-to only if the rule when route-to is matched
you can do like
pass bla.. prob 30% ..bla tag ROUTE1
pass bla.. prob 70% ..bla tag ROUTE2
pass bla route-to ($whatever1) tagged ROUTE1
pass bla route-to ($whatever2) tagged ROUTE2
Sorry about the syntax not being correct but you can use the man page
to do that.
I have not tested that but anyway it should work.
Hi,
pf can do outbound load balancing using route-to and provide the ext
interface and gateway ip like { ($ext_if1 $ext_gw1), ($ext_if2
$ext_gw2) } round-robin. But the algorithm is only round-robin which
may not be appropriate if the two links are asymmetric, say an 1MB
line and 256kbps line.
Is there any way to provide some ratio like 1:4 where out of 5
packets/bytes 4 will be via one link and one via other link?
I have gone through the docs and this feature does not seem to exist
any where, so if some one can give a starting place to look, where I
can do some hacking, that would also be fine.
