Hello !! tcp_outgoing_address could have a new parameter (or a new config option like tcp_outgoing_balance) for balance the outgoing packets using specific IPS, example: acl out_ips src_random 200.200.200.1 200.200.200.2 200.200.200.3 200.200.200.4 tcp_outgoing_balance out_ips and using round-robin or least-load .. balance packets between these ips !! i´m doing it using kernel/iptables modules statistic NTH / RANDOM !! regards, -- Sds.
