Routing Mode defines whether the device will accept incoming connections (passive opens) and/or establish outgoing connections (perform active opens):
0 (server)
Only incoming connections are accepted, the device never attempts to establish an outgoing connection to the network host. There is no restriction on which network host can connect to the device. Connection from any IP-address will be accepted as long as the remote host is connecting to the correct Port Number (PN) and Transport Protocol (TP).
1 (server/client)
Both incoming and outgoing connections are allowed. Outgoing connections are established with current Destination IP-address (DI) setting and current Destination Port Number (DP) setting. Exactly when the device attempts to establish an outgoing connection is defined by the Connection Mode (CM) setting.
2 (client)
Only outgoing connections are allowed, the device rejects all incoming connections. This is a newly implemented routing mode.
