Shouldn't matter.  If you are behind the firewall and it has only 576 to
the Internet, then path MTU discovery will force the firewall to reject
the packet and tell the computer to resize.  You can also use Wireshark
to verify the do not fragment flag is set.  As an experiment, you might
also try setting the MTU to 576 and trying that command again.
