[Snort-users] Plex and Netflix issues

I also use discord behind a PfSense box running snort and do not have any
sort of issues. I seem to recall that Hulu tended to trigger GID 137 on
SIDs 1 and 2 under the preprocessor though I never did figure out why. Are
you using snort on something like PfSense or a different OS? PfSense to
check blocked hosts would be Services > Snort > Blocked. If you see
would mean GID137:SIDs 1 and 2 would be good to turn off in the
interface-specific settings. It'll be in preprocessor.rules. Like wkitty42
pointed out though, you'll want to look at the alerts raised first before
jumping to disabling rules.

Hope this helps,
