Jeff,

I am the tester for a BBNCC product called a Mailbridge.  Mailbridges are a
type of gateway.  The way we have interpreted the TTL lower boundary condition
is that 1 is the lower limit for the receiving device.

For the case you stated, a datagram to be transmitted through a Mailbridge,
2 is the lowest limit for an incoming datagram.  The datagram will be
transmitted with TTL decremented to 1.
