Hi All
First time using FreeNAS.. long time Linux user, so I am familiar with Unix related OS's.
I am having a hard time changing the MTU on my FreeNAS 8.2. I believe I have followed the various directions found on this site, as well as through Google searches, but am unable to change the MTU from the default value of 1500 to anything else.
One of my system's ethernet adapters won't go higher than 7200, so I am trying to set all my systems to this.
I have gone to 'Networking' and selected 'Interfaces'.. added a manual entry for 're0' with the correct IP address, gateway, ect..
After restarting, I connected via SSH and ran ifconfig...
re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3899<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
ether 50:e5:49:52:40:1a
inet 192.168.1.122 netmask 0xffffff00 broadcast 192.168.1.255

ether 02:69:e3:00:04:0a
media: Ethernet 10Gbase-T (10Gbase-T <full-duplex>)
status: active
Since that did not work, I tried to change it through the shell...
[root@freenas] ~# sudo ifconfig re0 mtu 9000
Sorry, user root is not allowed to execute '/sbin/ifconfig re0 mtu 9000' as root on freenas.local.
Can anyone shed some light onto what I have not done correctly?
Many thanks in advance!
