I use 2 different methods to get it to work properly. i used to use method #1, but now method #2 works best. 1) set up 15 natd redirect_port entries for each ICQ machine, then tell that machine's ICQ that i'm using a firewall, not socks4 and not socks5. then it lets you enter the port range to use. i enter the range of the 15 ports from above 2) install a socks5 (www.socks.nec.com) proxy server and tell ICQ to use your socks5 server. this seems to work best now, since ICQ for Win95, DLL v1.3. if you install socks5, be sure to use its config file to limit who can open connections, otherwise anybody on the internet can use you to proxy connections for them. --Ludwig Pummer ludwigp@bigfoot.com ludwigp@chipweb.ml.org ICQ UIN: 692441 http://chipweb.home.ml.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
