http://askubuntu.com – I have to gigabit network interfaces which I have bridged. /etc/network/interfaces is: auto lo iface lo inet loopback # Set up interfaces manually, avoiding conflicts with, e.g., network manager iface eth0 inet manual iface eth1 inet manual # Bridge setup auto br0 iface br0 inet static bridge_ports eth0 eth1 address 192.168.88.2 broadcast 192.168.88.255 netmask 255.255.255.0 gateway 192.168.88.254 dns-nameservers 192.168.88.254 But the MTU is only 1500 myth@myth:~$ traceroute --mtu 192.168.88.1 traceroute to 192.168.88.1 (192.168.88.1), 30 hops max, 65000 (HowTos)
