AVM Access Server – 5 AVM Access Server Concepts and Functional Principles 77
5.3 Static and Dynamic Routing
Like any IP router, the AVM Access Server operates at the network pro-
tocol level (Layer 3 of the ISO/OSI reference model), and forwards in-
coming data packets from one connected network to another. To route
packets between networks, the Access Server needs the following in-
formation:
the logical address of the destination
a path to the destination
For a detailed explanation of TCP/IP addressing, see “IP address” on
page 127 in the glossary.
Information about the possible paths along which packets can be for-
warded is compiled in a routing table. Routing tables can be static, or
they can be generated dynamically.
Inactive HTTPS/
0.0.0.0 : 443/
0.0.0.0 : 443
TCP Activate this rule if you have
an HTTPS server (i.e. a
secure web server) in your
local-area network and want
to make it accessible from
the Internet.
Inactive ISAKMP (VPN)/
0.0.0.0 : 500/
0.0.0.0 : 500
UDP If you have configured VPN
connections, activate this
rule for the Internet
connection over which the
VPN links are carried.
Inactive AVM Web Server/
0.0.0.0 : 4000/
0.0.0.0 : 4000
TCP Activate this rule if you want
an AVM web server in your
local-area network to be
accessible from the Internet.
Remote configuration using
the web interface over the
Internet is not
recommended, since
communication with the web
server is not encrypted.
Instead, use a secure VPN
connection to access the
web interface.
