gif interface MTU stuck on 1280
« on: November 03, 2017, 07:57:53 am »
I have a Hurricane Electric 6in4 tunnel setup on pfSense 2.4.1.  The MTU for the interface is set to 1472 as well as on their web administration interface.

However, the following shows up in my routes and appears to be a bug that has resurfaced again.

2001:XXX:XX:XX::1   link#14   UH   0   1280   gif0

I cannot figure out the correct synax to change the MTU because I do not know how to account for the link#14 part in:

route -6 change 2001:XXX:XX:XX::1 -mtu 1472

Any thoughts?
