Hi Baptiste,
You put me in the right track, I had over-complicated my config, here is
the working config for anyone who's interested:
frontend servername:80
bind servername:80
bind servername:8080
acl int dst_port 8080
acl ext dst_port 80
use_backend server-int if int
use_backend server-ext if ext
default_backend server-ext
backend server-ext
option tcp-check port 80
option tcp-check port 8080
stick-table type ip size 1
stick match dst table server-int
stick on dst
server server-01-ext server01:80 check inter 5000
server server-02-ext server02:80 check inter 5000
backend server-int
option tcp-check port 80
option tcp-check port 8080
stick-table type ip size 1
stick match dst table server-ext
stick on dst
server server-01-int server01:8080 check inter 5000
server server-02-int server02:8080 check inter 5000
Thanks for your help, it's truly appreciated.
Cheers,
Nathan
