More info on the question:
Source IP          Dest IP           Port
10.11.11.11      10.11.12.13      80         Snort         WEB-CGI finger access

So I want this SNORT rule to ignore when DestIP is 0.11.12.13

Hello,

First find snort attack id number for this attack.

Please open the threshold.conf file. and goto last line and

suppress gen_id 122, sig_id 27, track by_src, ip 192.168.1.0/24

(gen id 122 and signature id 27 not collect from the 192.168.1.0/24 network)
