Yes, but that doesn't work for a SRC<->DEST type suppression. You can only make Snort blind to ALL things from that IP. You need to use BPF to do a SRC<->DEST suppression (basically not sending that traffic to snort at all.)
no ya don't ;) you've forgotten about "detection_filter" which is what the old in-rule thresholding is now called... eg: alert tcp $HOME_NET 21 -> $EXTERNAL_NET any (msg:"LOCAL.RULES FTP Brute-Force login attempt (1) -- BLOCKED DESTINATION"; flow:from_server,established; dsize:<100; content:"530 "; depth:4; pcre:"/^530\s+(Login|User|Failed|Not)/smi"; classtype:unsuccessful-user; detection_filter: track by_dst, count 5, seconds 300; sid:100000001; rev:5;) -- NOTE: No off-list assistance is given without prior approval.
