Med dedikert VPN maskinvare har man kapasitet til å koble seg til 32 andre nettverk. VPN kan settes opp som LAN-to-LAN eller for dial-inn ved hjelp av IPSec/PPTP/L2TP og L2TP over IPSec. AES/DES/3DES kryptering støttes, samt MD5/SHA-1 for autentifikasjon. VPN kan f eks brukes til BBS betalingsaksess IP for å kjøre kortterminaler over internett, og kutte analoge linjer eller ISDN løsninger.
S-modellene har ISDN over VoIP, som gir mulighet til å benytte ISDN utstyr over VoIP. Det gjør at man ikke lenger har behov for en fastlinje. I forhold til alarmsystemer for innbrudd, brann o.l vil da også dette gå automatisk over internett.
QoS funksjon gir mulighet til å reservere deler av linjen til spesifikke formål.
Vigor 2820 er selvsagt kompatibel for både Windows 7 og Snow Leopard!
