@Epaphus@mastodon.lo0.uk I was literally getting `SIOCSIFMTU: Invalid argument` for anything below 1500 with `ip link set eth0 mtu 1500` in the telnet shell.

Huh, although maybe it "just works". Once I set the server-side MTU to 1508 I can ping with packet size up to 1480 (1481 of complains it's too large). Experimentally setting the server side to 1608, and then binary chopping the ping size, largest supported is 1490 in the ping command.
