|---|---|
The result is that calling the isdn number 999901 from the number 3331234567, the call is rejected and an internet connection is established using the UMTS Key. The key acquires a dynamic IP address so the configuration of Dynamic DNS is needed to reach Abilis. Besides, a correct configuration of NAT resource may be necessary for example to reach a server located behind Abilis or to enable navigation toward internet from LAN. |
