28 CommPlete Communications Server
BCP
This field shows the status of the Bridge Control Protocol (BCP) for the port. Enable
BCP if the other end of the PPP link supports BCP.
IPCP
This field enables IP for the port. Select disabled if TCP/IP or PPP is not to be used.
Local Address
This field shows the IP local network address of the port. This address can be edited
only for LAN-to-LAN ports, and only if IPCP is enabled. For all client-to-LAN
connections, the local address is the same as the IP address of the LAN port. For
LAN-to-LAN ports, make sure the IP address is on a different network or a subnet of
any of the existing networks.
Remote Address
This field shows the IP network address of the port. It is the address assigned to the
remote PPP client. It must be on the same network as the IP local address. This field
can be edited only if IPCP is enabled for the port. It cannot be edited for client-to-
LAN ports if DHCP is enabled.
Subnet Mask
This field contains the mask used to specify the subnetwork part of the IP address.
For all client-to-LAN connections it is the same as the LAN network. See “IP
Addressing” on page 7.
VJ Compression
Select enabled to enable Van Jacobson compression of TCP/IP headers on the PPP
link. VJ compression is used by many PPP clients. Select disabled to disable Van
Jacobson compression. If IPCP and VJ Compression are enabled, a dial-in PPP client
that uses this compression method may experience greater speed than with VJ
Compression disabled.
Forward Broadcast
This field allows you to enable or disable forwarding of UDP broadcast packets onto
the port. Enable it if your UDP applications depend on the broadcasts. When for-
warding is enabled, the RASExpress server forwards to the selected port all UPD
broadcast packets that come from the LAN and from the client-to-LAN ports. For-
warding broadcasts on remote links increases the traffic on the links, so enable for-
warding only if necessary.
Multilink PPP
Menu path: Main Menu ➔ Configuration of Server ➔ Server Setup ➔ Multilink
PPP.
[ 1] Multilink PPP : enabled
[ 2] GroupEPD : c0a85a04
[ 3] Bundle Server IP Address : 000.000.000.000
[ 4] Bundle Server UDP Port : 582
[ESC] Previous Menu
Use this menu to set up Multilink PPP on the RASExpress server. The Multilink PPP
protocol bonds two physical ports to one IP address for greater bandwidth.
RASExpress 5.40 introduced MultiChassis Multilink support, which enables the
bundling of multilink connections across different RASExpress servers, as would be
