Can someone tell me how to filter this out of the portscan.log file?

Time: 10/29-15:10:06.363387
event_ref: 0 -> (portscan) TCP Portsweep
Priority Count: 5
Connection Count: 12
IP Count: 19
Scanned IP Range:
Port/Proto Count: 1
Port/Proto Range: 113:113

I only want to filter out what this thing considers scans from to TCP 113 on any host. is a Proxy server and is querying for TCP 113 because 113 is tied to IDENT (our proxy auth tracking mechanism).
