[-- Attachment #1 --] Hello, I have a freebsd box with a gif tunnel configured. I observed that even if ifconfig displays MTU 1500 for both gif and physical interface, 1300 bytes ipv6 packets transiting on the gif interface are systematically fragmented while transiting on the lower physical interface to 1280 bytes. Is it the normal behavior? Thanks. Konstantin _________________________________ Konstantin K.
