But.... it seems ubuntu applications send packets with the Don't Fragment bit set. So this really is an issue.
Anyway I wouldn't add any question to the installer. Changing MTU is for expert users (you have to yous registers even on windows). I suggest editing '/etc/network/interfaces' (and using 'man interfaces' to get help). It's simple and it s the right way to do network configuration. During install you can use either 'ifconfig' or 'ip'. If this is right, can the bug be closed? -- Can't set MTU during installation https://launchpad.net/bugs/32355 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
