How do I change the MTU for the WAN interface on the rCell?

1. Telnet into the rCell and go to:

cd /var/config[Enter]

echo 'mtu 1428' >> options[Enter]

save[Enter]

2. Telnet back into the rCell and verify the setting is there:

cd /var/config[Enter]

cat options[Enter]

*Look and make sure the setting is there.

3. Make a ppp connection and then type:

ifconfig[Enter]

*Look at the PPP0 link, and confirm it shows MTU:1428.

4. To remove it, type:

cd /var/config[Enter]

sed -i '/mtu 1428/d' options[Enter]

save[Enter]
