Windows Dial-Up Networking. ISDN remote configuration can be enabled by specifying an MSN/terminal device selection digit for it. In this case, the LANCOM router will accept calls on that MSN/terminal device selection digit and can be remotely configured via the ISDN con- nection.
DNS server – translates network names (www.lancom.de) or names of computers (www.lancom.de) to actual IP addresses. The LANCOM router can perform the functions of both a default gateway and a DNS server. In addition, as a DHCP server it can also automatically assign valid IP addresses to all of the computers in the LAN.
Page 42
Manual IP address assignment If the IP addresses in the network are assigned static ally, then for each PC the IP address of the LANCOM router must be set in the TCP/IP configura- tion as the standard gateway and as a DNS server.
All computers in the LAN can take advantage of the central Internet access of the LANCOM router. The connection to the Internet provider can be estab- lished via any WAN connection. Internet access via ISDN can be used as a backup connection for DSL, for example.
