just want to block the word “torrent” with layer 7 rule
my rule is
/ip firewall layer7-protocol
add name=torrent regexp=torrent
does this mean that this rule will block also word Torrent or tOrrent?
if not what is the correct rule?
No, these rules look inside packet content. It is not for blocking words or links.
Better look at these examples http://forum.mikrotik.com/t/how-to-block-torrent-100-only-2-lines-it-is-solved/66890/1
