<ul></ul><p>As of {2.1-RC1 (amd64) built on Tue Aug 13 14:23:15 EDT 2013 FreeBSD 8.3-RELEASE-p9}, GIF tunnels still default to 1280. I can override up to 1480 and that appears to work correctly, but I am seeing strange fragmentation problems no matter what MTU I use.</p> pfSense - Bug #2674: MTU setting hardcoded 1280 for gif interfaces and in RADVD confighttps://redmine.pfsense.org/issues/2674?journal_id=121962013-08-15T18:01:45ZChris Buechlercbuechler@gmail.com
