The following edits were also made to the snort.conf recently, and we suggest you make the same changes:
  1. Add Port 81 to HTTP_PORTS and also to the http_inspect preprocessor.
  2. Replace your stream5 global line with the following:
    preprocessor stream5_global: track_tcp yes, \
    track_udp yes, \
    track_icmp no, \
    max_tcp 262144, \
    max_udp 131072, \
    max_active_responses 2, \
    min_response_seconds 5
  3. Remove the line "base 36 no\" from the http_inspect preprocessor
