5.2.9 Point-To-Point Protocol Setup
This dialog box lets you setup the point-to-point protocol (PPP) options for each WAN port. Click on the PPP
button in the Router Setup dialog box to display this dialog box.
Point-To-Point Protocol (PPP) is a protocol commonly used in serial links (asynchronous or synchronous) for
the purpose of transferring packets between two end-points. This protocol basically allows the end-points to
negotiate use of link and protocol parameters in a standardized way and also allows for standardized
encapuslation of the packets being transferred between the end-points. The advantage of PPP is that it allows
for inter-operability between end-points (say routers) using PPP for their serial communication.
PPP Enable = [enabled l disabled]
Enables the point-to-point protocol on the specified WAN port. If you enable SLIP on a dialing WAN port, this
option will be grayed out. Either PPP or SLIP can be used at a given time. On a answering WAN port,
however, the RouteFinder is capable of detecting the type of connection, PPP or SLIP.
PPP Port Data Compression = [enabled l disabled
Enable or disable compression of packets that will be sent through the PPP interface associated with the
specified WAN port. Compression should be enabled on slower speed WAN links (speeds less that 57,600
baud) and if the modem is not doing any compression. At higher WAN speeds, compression should preferably
be disabled as the compression process may be slower than the link throughput rates. Compression should
also be disabled if the modem compression has been enabled.
PPP Port VJC Header Compression = [enabled I disabled]
The RouteFinder has compression for TCP/IP and IPX headers. In order for RouteFinder's to employ header
compression on a particular PPP link, even the peer needs to support the selected compression algorighm.
Enable this parameter for VJC compression on TCP/IP headers on the selected PPP link.
PPP Port CIPX Header Compression = [enabled I disabled]
The RouteFinder has compression for TCP/IP and IPX headers. In order for RouteFinder's to employ header
compression on a particular PPP link, even the peer needs to support the selected compression algorighm.
Enable this parameter for CIPX compression on TCP/IP headers on the selected PPP link.
