Maquerading

Hi all

I have 2 wireless cards. WLAN 1 for internet and WLAN2 for private network. I have masquerading setup for the internet to work, which is fine. I have setup all routing for the WLAN2, but would like to share files on My PC via WLAN2. Can I setup masquerading to run on just WLAN1?

Whom do you want to share file on the computer connected to the local network ?
Masquearading is used for local network, to hide local network hosts after one IP address of the public interface.
