Slow video streaming

Welcome to the forums. A quick test: Turn one of the HA units off. I found in v4.2.13 (I think) that having the units in A-A slowed down throughput. I never put a ticket in, just switched to A-P mode instead.

Hi Alex. Welcome to the forums. Use the search link (above) and look for youtube slow/stalled connection issues. You did not indicate which firmware the 200Bs are running. But on 4.0 MR3 (and may be earlier) firmware, slow or stalled video streaming may be related to how the fgt buffers incoming " files" (if the fgt is in proxy mode) and/or if disk caching is enabled (don' t have fgt in HA so don' t know if disk caching is even allowed in HA). In 4.0 MR3 you will want to look at Protocol Options (under Policy->Policy->Protocol Options), in 5.0 I think the file size option is controlled by DLP. Edit: sort of an after thought, in additional to what Bob pointed out and what I wrote (above)...guess we are all assuming there is nothing wrong with the WAN connection, but you should rule that out as being part of the problem (e.g. MTU, duplex/speed mismatch, etc.).

I' m running 4.0 MR3 in Actives-Actives mode I may try to change to Actives-Passives to see if it help, Can I do this change live without affecting users? I also add the URL of the website from witch we want to stream into the exempt list of the cache Under Policy/Policy/Protocols Options, under HTTP I have Oversised File/EMail to Pass and threshold I changed to 1 to test (was 10)

Changing from A-A to A-P had no effect, I must add, that it' s not video from youtubes that are problematics, it' s video from instatscout.com, which use JW Player to stream video. so far nothing did help

Hi, For me: config webfilter content-header edit 1 config entries edit " video/.*" set action exempt next edit " audio/.*" set action exempt next end set name " Liste-content-header" next end

I tried donnat suggestion, didn' t help, tried to create a separate fw policy as dave suggest, still no help, I' m starting to think it may be something with my inet provider, To answer Maik question, I dont use comfort clients, should I? If I was to set comfort client, should I do it under HTTP for video? This website is somewat critical for our business, we are a professionnal soccer team and scouting agents use this to scout new prospect players. Thanks everyone for trying to help me, if you have any others suggestion for me to try, please go ahead.

Have you performed any troubleshooting steps to rule out any possible MTU/duplex/speed mismatch issues on the WAN connection? Is the WAN connection on DSL?

My connection isn' t a DSL, it' s fiber optics, I actually do have 3 connection to the internet, I have 1 60Mb and 2 30Mb connection comming in the fortigates units. I can' t find where in the fortigate I can check the MTU/Duplex/Speed

Also, have you tried to circumvent the Fortigate by using a PC directly connected to your fiber? Maybe the problem is on the line or with your ISP.
