Networks and Firewalls
One of the major obstacles when trying to remotely control something is the fact that the
Internet Service Provider (ISP) forces us to use dynamic IP addresses. We can never know,
from time to time, which IP address our modem / firewall / router has on its outside interface
(the IP address you will try to connect to). Most people use NAT routers that translates IP
addresses on the inside (your little LAN) to one common IP address on the outside using port
conversion.
At the remote end the router must be configured so that port 80 (default settings) is directed
to the Antenna switch which should have a static IP address. If you have other remote
controlled equipment connected to the router port 80 is probably already in use and you need
to change the webserver port from 80 to something else. In the example below where we
have setup the Linksys router we have used port 8000.
If you do not have fixed IP from your Internet Service provider you will probably also need to
use a dynamic dns service (see earlier chapter above) so you can use a host name instead of
a IP-address when you browse the unit. If you already have a dynamic dns service in use for
any equipment connected to the same router, you do not need to have any specific service for
the Antenna Switch.
The following default IP ports are used (changeable)
