For SNC connections to be possible with SAProuter, SAProuter must be started with this option: saprouter -r -K <mysncname> (AS/400: saprouter '-r -K <mysncname>' ). There must also be a KT entry in the route permission table specifying that connections with a certain host (whose SNC name is known) should be SNC connections. <mysncname> is the SNC name of the host on which the SAProuter is running.
