Remote Network Connections
AVM Access Server – 6 AVM Access Server for Experts 107
6.4 Remote Network Connections
The AVM Access Server allows you to connect entire remote LANs to the
local network. The Access Server provides the following features for re-
mote network connections:
IP routing
direct ISDN connections (with up to 30 bundled B channels)
VPN connections over the Internet
NetBIOS spoofing
As for remote user connections, the two locations can use IP addresses
in the same subnetwork. In this case, the Access Server performs proxy
ARP. Addresses in different subnetworks are recommended, however.
Example: The London office has the subnetwork 192.168.20.0/24, and
the main office in Berlin has the subnetwork 192.168.10.0/24.
6.5 Windows Name Resolution, File and Printer
Sharing
The AVM Access Server does not route broadcasts. As a result, Win-
dows name resolution cannot be performed automatically among the
workstations, as it is in a LAN. If you want to address shared resources
by their NetBIOS names, you must either operate a WINS server, or en-
ter the necessary computer names in the file “LMHOSTS” on each com-
puter.
When interconnecting Microsoft networks with Active Directory, it is
recommended that you operate domain controller at each site. For de-
tailed instructions on configuring WAN-linked Microsoft networks, see
the “Active Directory Branch Office Planning Guide” from Microsoft. For
a link to this document, see the section “Further Reading” on page 115.
6.6 Filter and Forwarding Profiles
You may choose to restrict access over remote network and Internet
connections using IP packet filters. Filters can be applied to specific re-
mote users or networks, as well as globally, to all remote users and
networks and all network adapters. If a packet matches an “Accept”
rule in a network or user-specific filter profile, it cannot be dropped by
any rule in the global incoming or outgoing filter profile.
