Using The Sun SNDR Software in a Firewall Environment

You can use the Sun SNDR software with any enhanced network product that Sun offers. Port 121 must be available for use by the Sun SNDR sndrd daemon.

You can use IP masquerading. SNDR uses connection-oriented service (COTS) based remote procedure calls (RPC; that is, TCP). The RPC part of the packet does not contain any address information.
