Slow roundcube from internet, fast on internal network
i have problem with slow roundcube/kolab behind pfsense (nat/firewall/router/default gw). RoundCube/Kolab is in VM on different host centos. That different host centos has a different default gw (not pfsense). Roundcube is fast on internal network 192.168… but from internet over carp/nat/firewall (port 80) is very slow (refreshing mail, new mail over 10sec).
router from provider
pfsense 2.2.2-RELEASE (i386) on pc behind router from provider
centos host, kolab/roundcube on virtualbox vm, (latest versions)
