Port Type
Select the type of connection the port is to be used for: Client-to-LAN or LAN-to-
LAN. Select Client-to-LAN if the PPP peer is a dial-up client. Select LAN-to-LAN if
the PPP peer is a dial-up client or another router. If you change the connection type,
be sure to change the IP address also.
SLIP
This field shows the status of the Serial Line Internet Protocol (SLIP) for the selected
port. Enable SLIP if you have SLIP clients dialing into the RASExpress server.
Data Compression
Select Enable to enable PPP data compression for the port. Enable data compression
only if the data link is slower than 57,600 bps and the modem is not doing any data
compression. Disable it if the data link is 57,600 bps or faster or if the modem is doing
data compression.
