Hi,
I'm sorry, but I can't exactly understand all you wrote. So...

May be near, but i can't catch RPORT parameter :( I've read the manual 
about RPORT.

Yes.

Very, very near, may be here. The main my "headache" is big files over 
http and ftp. And i'd like to route them (big files) to the slow link 
with big latency, whereas "reading" people will be able work through the 
fast link.

My network is simple: I have two gateways with two links to ISP 
connected together by private network. Both gateways have two 
interfaces: one to ISP and one to internal network. I thought to start 
two MASTER-DeleGates on the gateways and one specialist DeleGate as 
proxy for clients. But i couldn't find appropriate configs from the 
dalegate's manual.
Help me, please.

Cheers,
Alex Bel.
