james: i found that "Linxu Firewalls" by Robert L. Ziegler, 2nd Edition, New Riders, ISBM 0-7357-1099-6, to be the most usable book on this subject. the book does contain some rather glaring errors, imo, but i was able to get around them by using information in the book (as to how things work sort of information). nat is weak; in fact, his example would not work for me. but i did get my lan working okay anyway via forwarders. everything on my lan works with the outside world (ssh, web, ftp, ping, time, mail), and the outside world can see my web, ssh, and mail server. limited ping is available
