| What firewall software (Opensource) would you advice? Or do I have to | choose another OS? Personally I would favour using either ipf (ipfilters) or ipfw. Both are compiled into the kernel or can be loaded as modules. ipfw is probably easier to use for a newcomer, as the rule ordering is easier to understand, however ipf has some really good features, especially if you are using nat (it can do nat in the kernel using ipnat afaik). The homepage for ipf is http://coombs.anu.edu.au/~avalon/ip-filter.html and there is a really good tutorial at http://www.obfuscation.org/ipf/ipf-howto.txt ipfw doesn't require quite as much explanation, there is a page on http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html which covers it. Although 'man ipfw' will probably provide most of what you want.
