Slow video streaming

[AlexImpact]

Hi, I need your help, I have 2 fortinet 200b in HA and a 100Mb Internet connection. But watching videos online often lag really bad, stopping every time to buffer, watching a 10 minutes video is like 30 minutes of buffering, watching the same video from the same source on a much slower connection like at home is no problems at all. Can anyone help? most documents I found online are to restrict video streaming, nothing on how to speed it up. But the business I work for need to be able to reliably watch these videos. Thanks

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,

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?

[AlexImpact]

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

diagnose hardware deviceinfo nic <port name>

That' s from memory. It may be a bit different.

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.

[Dave_Hall]

Someone on here pointed out the MTU value for fiber connections may be need to be set lower than the default 1500. If the 3 connections are from 3 different ISPs then the connections may have/need different MTU values. With 3 connections to the Internet you could always try playing around with policy routes -- direct instatscout.com traffic through one of the connections, to see if that helps, or at least assist with troubleshooting.
