[ale] MTU's and DSL's

[Dow_Hurst]

I've had to use MTU=1412 for the network behind a NAT firewall connecting via PPPoE over DSL since the PPP tunnel imposed a lower maximum value for the MTU.  Might depend on the protocol being packaged too as to what is most efficient.

Does NAT impose some MTU changes? I just had to set the MTU on a web
server down to 768 to get the traffic passing back out the firewall and
up a Speakeasy DSL line.
