Sharing the load: Address pools

Your users have bookmarked your $webserver, load goes up.

Solution: more servers and a redirection

webpool = "{ 192.0.2.214, 192.0.2.215, 192.0.2.216, 192.0.2.217 }"

rdr on $ext_if from any to $webserver port $webports -> $webpool \
       round-robin sticky-address
