Hi list, As i've already seen on Linux Kernel, MTU can be specified by network interface and by IP protocol through sysctl (don't know if it is the best way to do, but it's efficient) .
For instance : sysctl -w net.ipv6.conf.eth0.mtu=1280 This does not apply to L2 MTU on network interface itself but only on IPv6 traffic/packets. Is there a way to handle this on OpenBSD ? Regards, Christophe.
