2 ISP and port forwarding

Hi,

I need help with port forwarding from one mikrotik to two different internal servers and ip ranges.
My setup is:
one adsl modem in bridge mode, one mikrotik RB433 and two servers.
The RB433 is connected from eth3 to the adsl modem, eth1 is going to server1 on 192.168.65.200 and
eth 2 is going to server2 on 192.168.88.200.

Masquerading is already setup and under interfaces I have two PPPOE connections with two different ISP accounts.
Port forwarding is working fine for the one server (192.168.65.200) but how do I port forward traffic to server2
landing on ISP2 interface/public ip.

The reason I am doing it like this is because you cant forward traffic destined for port 443 (or any port) coming in from one public ip to two different
servers, and changing the listening ports on one server is not n option.

I hope anyone can help me

when you have setup like this you have to mark connections coming from one ISP and from second ISP accordingly to make sure that replies are sent out the same connection they came in. Nothing else guarantees that connection will work properly.

in wiki PCC example it is described.

Thanks, I will check out PCC
