Overview	The OfficeConnect Remote 840 can be configured as a router to forward
	packets between the local LAN interface and one or more remote sites. A
	forwarding table is maintained that specifies which interface to route an
	IPX packet based on the destination IPX network number.

Entries into the forwarding table are either static or dynamic. Static entries are based on the LAN's network number, the remote site WAN interface number, and user configured static routes. Dynamic entries are added when RIP is enabled and routes are learned from neighboring routers.

To configure IPX routing, IPX must be defined on both the LAN interface and one or more remote sites. On the LAN, an IPX network must exist with a specified IPX network number. On the remote sites, IPX forwarding needs to be enabled, and the WAN interface address need to be configured. The WAN interface can be unnumbered (set to 0), numbered, or dynamically learned (if PPP is used).
