rdr and pass out

[Mipam]

Hi,

I wish to perform load sharing between some webservers.
So i have this in pf.conf

I also whish to normalize traffic:

set state-policy if-bound

scrub on $ext_if all fragment reassemble reassemble tcp random-id

web_servers = "{ 10.0.0.1, 10.0.0.2, 10.0.0.3 }"
rdr on $ext_if proto tcp from any to any port 80 -> $web_servers \
    round-robin sticky-address

However, with the rdr rule do i also need to ass a passout rule
for the ext_if (i also wish to use modulate state)?

Would it also possible to assign a virtual address and direct any traffic
to that ip on port 80 to the web_servers?
Bye,

Mipam.
