Thanks to the help I got from the great SuSE gurus on this list I finally have my entire email system set up and debugged. A little about my LAN. I have 5 machines on the LAN. 4 of the machines POP mail from one server running SuSE Pro 9.1. This machine sends and receives mail via SMTP. I am now ready to set up a firewall. When I set up the firewall using YAST what settings to I have to make to do these things ..... Allow the SuSE box to still send and receive mail with SMTP ... Allow all the other 4 machines to send mail to the mail server over the LAN .. Allow NFS to work between the 5 machines on the LAN ... Allow all the other 4 machines to access a yet to be set up MySQL database over the LAN ... All machines are set up with static IPs and have properly configured /etc/hosts files in place. Other then mail in and out via SMTP, I want the SuSE box closed to the net. All comments welcome. john ################################### # John N. Alegre ###################################
