Remote operation via the Internet
The appropriate connection is required (e.g. DSL router) for remote operation via
Internet. Setting up Internet access is not described here.
•
The example here were created using the Siemens Gigaset SX763 router (see
Section 7.3.5). Workflow, terms and functionality may differ when using other
products.
•
The router must support NAT/PAT, DynDNS and DHCP as an option.
•
The web server supports HTTPS (Hyper Text Transfer Protocol Secure).
Web operating pages are transmitted secured and encrypted.
IP address, subnet mask and DHCP are set up under Local Network in addition
to other settings:
•
The IP address router is fixed.
•
The subnet mask defines the size of the subnet.
•
The router assigns the DHCP clients (e.g. the PC on the local area network)
an IP address from a selecting setting range ("First issued IP address" through
"Last issued IP address") if set as DHCP server.
•
The "Default gateway" is typically the router's IP address as well.
•
The "Lease time" defines how long a client maintains the IP address received
from the DHCP server (the DHCP server regularly renews the client IP ad-
dresses).
In the example, the router has a set IP address of
192.168.2.1
and receives subnet
mask
255.255.255.0
. As a DHCP server, it renews the IP addresses of the DHCP
clients every 30 (in the above example) minutes. DHCP clients are assigned
addresses from a range of
192.168.2.100
through
192.168.2.199
. The router is the
gateway between LAN and Internet.
