Configuring Port Forwarding

An easy way of accessing the Aastra CTI Touch web application is via selected port for-

warding to port 8080 of the communications system.

Note

The password is transmitted encrypted when logging into the Aastra CTI Touch web

application. All displayed content is transmitted via the unencrypted HTTP protocol.

If the users e.g. are using an internet connection via the unencrypted WLAN of an in-

ternet café, you should configure a secure VPN connection via VPN (see Configuring

VPN with PPTP).

The following instructions assumes that the company LAN or the communications

system is connected to the internet via a DSL router.

1. If your internet connection is not configured with a fixed public IP address, you

have to set up an account on the internet website of a DynDNS service. This kind

of service links the changing public IP address of your DSL router with a DNS

name. Open the Network: DynDNS page in the Configurator and enter the login

information for the DynDNS service. Alternatively, you can – if possible – configure

the DynDNS service on the DSL router as well.

2. Configure port forwarding on the DSL router. You have to divert the TCP port 8080

to the IP address of the communications system.

3. Start up a web browser on the smartphone. Enter the DynDNS name you set up in

the first step, into the address input field of the browser. Add the port number

8080 after a colon. Example:

http://mycompany.dyndns.org:8080

The login page of the Aastra CTI Touch web application appears (see Login).
