Changing MTU on the gui does nothing
I tried this on pfSense 2.4.4-RELEASE-p2, did a fresh install too to make sure it isn't a config issue, but there is something strange showing up on my install
On the interfaces / WAN, there are two fields: MTU and MSS
I tested the changes using this site: www.speedguide.net/analyzer.php
I changed MTU to 1440, visit speedguide and nothing happens
BUT if I change MSS to 1440, on speedguide the MTU field shows correctly, and MSS as 1400
Is this a bug or I am understanding it all wrong?
Thanks, have a nice day.
understanding it all wrong
Ding Ding Ding - you win yourself a cookie ;)
Google mtu vs mss
Please enlighten me in one detail
If I leave MTU on default, and on my Desktop Ubuntu I change my NIC mtu to 1440, speedguide shows the value I entered
I revert my Desktop NIC to 1500, and change pfsense MTU on the WAN interface to 1440, no changes are seem on speedguide
But if i change the MSS value of the WAN interface on pfSense, them the MTU value changes to 1440 on speedguide
Why changing the MTU field on the gui din't show on speedguide, but MSS did actually reflect the value I entered for MTU?
Because they are completely different things.. Again google mtu vs mss..
