Opening Modem Ports ADB VV4820 and ADB VV2222
The fastweb modems/routers in question are manufactured by ADB broadband and have similar firmware to the ADB DV2200 with the difference that they support voip and a few more features that we will not, however, go into in this short article
The ADB VV4820 is Fastweb's flagship router, it supports VDSL2 fiber and 5Ghz Wi-Fi, has two Voip ports, two USB 2.0 and 4 Gigabit ethernet ports
ADB broadband VV2222 is the dedicated modem for ADSL2 customers with VoIP
In order to receive incoming connections such as VPN, web servers and access to video surveillance cameras it is necessary, as with all other routers, to have a public IP address, in the case of fastweb you can request it from the call center, which will activate it in a couple of days
You also need the forward (the opening) of ports on the router that direct to the computer running the service concerned, such as those described before or even Emule or Torrent, which without the opening of ports remain "firewalled" or with low id
To access the ADB VV4820 router we use User: admin Password: admin
For the ADB VV2222 User: fastweb Password:
ADB DA2200 User: admin Password: admin
For the remaining procedure you can rely on what is described in the guide for the ADB DV2200 modem since the ADB firmwares are (at least in these parts) very similar
The only difference you may notice is that the type of interface to be used for port forwarding might be ATM in the case of an ADSL modem

Signal Improvement
Over the days, we noticed that during phone calls, the errors on the router increase and that we often drop theline, the solution was to install this splitter:
Enerdom SAPV120 VDSL2 splitter: connection, installation and improvement of signal SNR and attenuation
Static IP addresses
Pcs or devices running the services must use static IP addresses (which do not change over time) you can configure them in the operating system or in the router, we will cover the configuration in another guide
