- Remote access Address assignment is made possible by a special entry in the IP routing table. 255.255.255.255 is specified as the network mask as the IP address to be assigned to the remote site in the 'Router-name' field. In this case, the router name is the name, with which the remote site must identify itself to the LANCOM. In addition to the IP address, the addresses of the DNS and NBNS servers (Domain Name Server and NetBIOS Name Server) including the backup server from the entries in the TCP/IP module are transmitted to the remote station during this configuration. So that everything functions properly, the remote site must also be adjusted in such a way that it can obtain the IP address and the name server from the LANCOM. This can be accomplished with Windows dial-up networking through the settings in the 'TCP settings' under 'IP address' and 'DNS configuration'. This is where the options 'IP address assigned by server' and 'Specify name server addresses' are activated.
- Internet access If Internet access for a local network is realized via the LANCOM, the assignment of IP addresses can occur in a reverse manner. Configurations are possible in which the LANCOM does not have a valid IP address in the Internet and is assigned one by the Internet provider for the duration of the connection. In addition to the IP address, the LANCOM also receives information via the DNS server of the provider during the PPP negotiation. In the local network, the LANCOM is only known by its internal valid intranet address. All workstations in the local network can then access the same Internet account and also reach e.g. the DNS server.
Windows users are able to view the assigned addresses via LANmonitor. In addition to the name of the remote station, the current IP address as well as the addresses of DNS and NBNS servers can be found there. Options such as channel bundling or the duration of the connection are also displayed.
