We had 'ttl: < 5;' and 'ttl: > 6' support before. I just
added support for : 'ttl: 5-10' (or even 'ttl: - 5;' or
'ttl: 5 -;' which is equal to '0-5' and '5-255' range), let
me know if that's enough for your needs.. :-)
You will need to cvsup current cvs tree. (or wait a day and
fetch http://snort.sourceforge.net/snort-daily.tar.gz :))
