The ethernet standard for MTU is 1500. This applies to all ethernet interfaces except for a PPPoE on WAN connection.
If you have a PPPoE connection on the WAN interface, m0n0wall defaults to an MTU of 1492, but it can be set to other values - usually lower.

If you are manually setting an MTU for VPN, also make it under 1500 to allow for headers. 1492 is good for a lot of things... But for VPN over PPPoE, you need less. I set 1400 if there is ever a problem.
