The CSNET X.25 network had to go through international X.75 gateways
(recall the primary reason for the CSNET X.25 network was to connect
international IP networks to the US).

My memory is that they were a serious pain.  I believe they permitted
only two packets inflight over a connection -- and I think packets were
either 128 or 256 bytes -- so we had to fragment IP datagrams and *slowly*
relay them.
