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

Time: 10/29-15:10:06.363387
event_ref: 0
11.22.33.44 -> 55.66.77.88 (portscan) TCP Portsweep
Priority Count: 5
Connection Count: 12
IP Count: 19
Scanned IP Range: 9.10.11.12:13.14.15.16
Port/Proto Count: 1
Port/Proto Range: 113:113

I only want to filter out what this thing considers scans from 11.22.33.44 =
to TCP 113 on any host.  11.22.33.44 is a Proxy server and is querying for =
TCP 113 because 113 is tied to IDENT (our proxy auth tracking mechanism).
