This Shorewall of yours is perfect. In the beginning of November 2001 the cable comp. came to install my cable modem. Then every thing started; I needed a firewall-router-nat-cheap-stable-easy-... Some friends of mine told me to use Linux, OK for me. After a month of installing, config..... without any luck There it was, Shorewall 1.2.12, at first its like does diete-pils, many ????????? Installed even better then a MS... Till yesterday I had an uptime of 481 days (RH 7.2 + Shorewall 1.2.12) To day I reinstalled Linux RH 7.3 and shorewall 1.4.4b, and it works directly. Many THX and Good luck. Bram
