oops! i see sf2 also open unpriviledges ports! i
suggest to block all 
icoming ports by default otherwise open only
priviledges ports! using squid 
is not the solution, because iptables can handle this
simple thing.

bug in sf2 documentation:
- section 11. default value is no BUT my clients can 
access port >6000 for 
IRC!
