The USG20W-VPN is physically the same, with the addition of three external antennas. It is passively cooled, so runs silently. It comes with an external power supply and adhesive rubber feet for desktop use. Its gray metal enclosure with red trim measures 8.5″x5.63″x1.3″. The USG20-VPN has the same look as the USG20 and USG40. With that out of the way, let’s dig into the USG20-VPN. The USG40 has even higher throughput than the USG20-VPN, an optional RJ45 port that can be used as a second WAN port, plus support for Anti-Virus (AV) and Intrusion Detection and Prevention (IDP). Essentially, the USG20-VPN is a faster version of the USG20, with the addition of an SFP port. The key differences between these product lines are summarized in Table 1. The USG20W-VPN adds dual-band AC1750 802.11aa/b/g/n/ac wireless connectivity. The USG20-VPN offers many of the same features as the USG20, with improved performance over the USG20. The “VPN Firewalls” include the USG20-VPN and USG20W-VPN. The USG40W adds single-band 802.11b/g/n wireless connectivity. The current USG40 also has an improved multi-core processor. In addition to VPN and Firewall features, the USG40/USG40W also support Content Filtering, Anti-Spam, Anti-Virus, and Intrusion Detection/Prevention UTM features. The “Next-Gen Unified Security Gateways” include the USG40 ( reviewed in November 2014) and USG40W. The USG20W adds single-band 802.11b/g/n wireless connectivity. In addition to VPN and Firewall features, the USG20/USG20W also support subscription-based Content Filtering and Anti-Spam UTM (Unified Threat Management) features. The “Unified Security Gateways” include the USG20 ( reviewed in May 2011) and USG20W. But with three different families, buyers can be easily confused. ZyXEL has steadily expanded its security appliance / firewall product lines. Introduction Update 7/29/16: Client to Site IPsec works
