How to split connection from LAN to WAN and WAN to LAN??

[agismaniax]

I have two ISP connection.
Previously, I'm testing with one ISP and I can access FTP (passive) and HTTP from internet to my internal server very fast.
After I add another connection, the connection from internet to my internal server seems slowing down and almost down to zero Kbps.
But no problem at all from my internal to internet.

I didn't change anything in FTP/HTTP server, I only do:

• enable BIZNET interface
• change gateway on some LAN rules

I want to make split connection:
FTP/HTTP server from/to ISP #1 (WAN)
Selected users (EDP) to ISP #2 (BIZNET)
The rest of users to ISP #1 (WAN)

What should I do to split the connection for 2 ISP?  ??? ??? ???

After that testing, i'm switching off BIZNET interface and set back all changed rules to previous state, but download process from my FTP/HTTP to internet is still slowing down. Upload still fine. I dont know what's wrong with it.

Could someone give me some advice?

Able to split outgoing connection from LAN to WAN.
Still confuse about incoming connection.

Lack of documentation and support here.  :'( :'( :'(

Able to open incoming connection from internet to lan for spesific port via Port Forward and NAT 1:1 via WAN interface.

Some questions:

• FTP download is very-very slow on WAN interface from internet (already open TCP FTP and TCP 55000-60000 for Passive FTP).
• Unable to ping the OPT1 interface from any (already open ICMP connection to it's IP).
• Unable to ping virtual IPs on OPT1 interface from any (already open ICMP connection to it's virtual IP).
