@derreckbercier said in Pfsense blocking Livestream:
i've been troubleshooting this, and part of the problem is since switching to pfsense it has given my other networks 1gb access to the niq, my old router only the main lan was at 1gb every other network was at 100mb. So something on my other network is hogging up all the bandwith on that switch and i'm trying to narrow it down. Thanks for everyone's help on this problem so far.
If you are uploading to a remote streaming host, but then your local LAN clients are simultaneously downloading the stream from that remote host over the same Internet connection, you can use it all up to the point the ACKs from the remote host do not make it back to your streamer PC in a reasonable time. So your streamer PC slows down and slows down and slows down trying to get the connection going. Uploading requires enough bandwidth on the download side for ACKs from the remote receiving end to get through. If you have tons of local users sucking up all the download bandwidth viewing the stream, then nothing is left for your uploading PC to receive its ACKs. Giving those "hungry" local LAN clients a gigabit pipe to suck from will exacerbate the problem. If they were all formerly sharing a 100 megabit pipe into the central switch, they could have been partially moderating each other so that the sum was not overwhelming to your uploading stream.
Don't know your situation precisely, but from your description it sounds like you were uploading to a remote host on the web that your local clients viewed from. Is that true, or do I have it wrong?
If I've correctly guessed your setup, then you can benefit from traffic shaping on pfSense that gives your uploading streamer PC priority bandwidth.
