RE: Disable bad bugfix in 9.405-5 "Fix [NUTM-2840]: [AWS] UTM ignores MTU sent by DHCP server"
THANK YOU, I too have been fighting with strange issues the last couple weeks. Glad I decided to look here.
I made the fix and was able to set the MTU to 15000 and all is back to normal.
Disable bad bugfix in 9.405-5 "Fix [NUTM-2840]: [AWS] UTM ignores MTU sent by DHCP server"
Do not do this if you don't feel comfortable messing up your UTM.
I'm pretty shure this voids the warranty. But my UTM is pretty useless using a MTU of 576 from my ISP.
The 9.405-5 upgrade introduces a mandatory, non disable, usage of the MTU provided…
