Forums Connection Issues Can't receive DCC in LAN

I'm using a LAN without NAT, which means I must connect through a SOCKS proxy.

I've set "both" in mIRC's firewall setting, but it seems every time someone send me a file through DCC, mirc makes a connection NOT through proxy, so it always fails.

I'm using mIRC 6.03 on Winxp with a SOCKS4 proxy server.

Can anyone help me? Thanks.
