You can change the MTU value by editing the below file.

/etc/sysconfig/network-scripts/ifcfg-eth0

You have to put MTU="1450"

save the file and restart the network for IPV6 use IPV6_MTU="1450"

Hello,

Note that you may want to consult with your data center or hosting provider if you have no experiencing modifying network configuration files, as a mistake in editing could result in your server failing to respond.

Thank you.
