want expert solution to setup muti dynamic ip for two nic
 

Many people have many questions about using multiple ip with Flashfxp, but I think this could be quite special one.

I have two nic. Only the 1st nic is directly connected to ISP which grant dynamic ip. I want to use the 2nd nic to get the dynamic ip from isp via the 1st nic which is configured to be a routable nic or being set as a gateway, so that the 2nd nic can connect to ISP to get the dynamic ip.

If this could be done, then I can bind other sessions of Flashfxp to use the 2nd dynamic ip to connect to remote ftp server.

Any comment/advice is appreciated.
