Chapter 6: Providing dial- up access

6.1.2Settings for TCP/IP

Each active RAS user must be assigned an IP address when using the TCP/IP protocol.

		LAN of the head office.
		IP: 10.0.1.0
	EN	Remote
	EN	workstation
		workstation
		IP:
		10.0.1.101
		VPN or ISDN
		connection
		ISDN adapter
	10.0.1.100	User: 'SAMPLE'
	(0123) 123456	(0123) 777888

This IP address can be permanently assigned when setting up a user. However, it is simpler to let the LANCOM router automatically assign free IP addresses to users when they dial in. In this case you only need to specify the IP address range that the LANCOM router should use for RAS users.

During both manual and automatic IP address assignment, please ensure that only free addresses from the address range of your local network are used. In our example, the IP address '10.0.1.101' will be assigned to the PC when con- necting.

This IP address makes the computer a fully-fledged member of the LAN: with the appropriate rights, it can access all of the other devices in the LAN. The same applies in the other direction as well: computers in the LAN will also be able to access the remote machine.

6.1.3Settings for IPX

Two IPX network numbers must be provided for remote access to an IPX net- work:

the IPX network number of the head office

an additional IPX network number for the higher-level WAN
