What I was thinking was this commit to head and the PR mentioned there: http://svn.freebsd.org/viewvc/base?view=revision&revision=186948 Note that 7.1 or earlier won;t have the prison_check_ip4() function, different byte order requirements etc (and not IPv6 support). It's s pretty short thing but has to be "converted" correctly. I might be able to do that later today. /bz -- Bjoern A. Zeeb It will not break if you know what you are doing.
