# Grandstream GWN7003 Review: PoE VPN Router, Who It Suits and Who It Doesn't > Grandstream GWN7003: 10 GbE, SFP, 2 PoE outputs, IPsec/OpenVPN. Covers PoE budget and no-Wi-Fi caveats.

Its listed port count is 11: ten GbE RJ45 ports and one Gigabit SFP port. It targets small offices and branch networks. Its standout feature is two PoE output ports, which can power IP phones or access points over a single cable. Built-in VPN (IPsec, OpenVPN and others) and QoS are also supported. As of October 8, 2026, Amazon. co. No wireless LAN function is listed. If you need Wi-Fi, you must connect a separate access point. This is not a replacement for a home Wi-Fi router. ## Connectivity & Compatibility The specs list one PoE input port (IEEE 802.3af/at) and two PoE output ports (48V passive or IEEE 802.3af). Passive PoE and IEEE 802.3af are different methods. Standard 802.3af devices are fine, but if you plan to power equipment designed for passive PoE, check its voltage and polarity requirements. | Item | Detail | |---|---| | Ports | 10x GbE RJ45 + 1x Gigabit SFP | | PoE input | 1x IEEE 802.3af/at | | PoE output | 2x (48V passive or IEEE 802.3af) | | VPN | Built-in (IPsec, OpenVPN, etc.) | | QoS | Supported | The total PoE power budget is not given in the data provided. Two low-power IP phones are probably no problem, but if you plan to power two high-draw access points or cameras, check the manufacturer's spec sheet first. The SFP port suits fiber links or a link to another building. SFP modules are usually sold separately, and the type (such as SX or LX) must match the far end. ## Product Info As of October 9, 2026, Amazon. co. Prices change with sales, exchange rates and stock, so check the product page for the latest. For eBay we only have a search link, not a price. Seller and fulfillment are both shown as Amazon Global Store, so it may ship from overseas. Check the product page for warranty terms and domestic repair support, and for exactly what accessories are included. In the market it sits between a home router and a full enterprise firewall, aimed at SOHO and small offices. ## Best Use Cases - Small office administrators: ten GbE ports plus PoE output reduce cabling and power strips. - Anyone needing remote or site-to-site access: the built-in VPN lets you reach the office network securely, and QoS can prioritize video calls. - Users with a few PoE devices: up to two phones or access points can run without separate power adapters. - Not a fit for: those wanting built-in Wi-Fi, 10GbE or faster ports, or networks of several dozen devices or more. ## Before You Buy First, assume there is no built-in Wi-Fi. You will need a separate access point, though the PoE output can power it over the same cable. Second, the total PoE budget is not listed in our data. Using both ports with high-power devices may exceed it, so compare the manufacturer's budget with your devices' consumption. Third, IPsec and OpenVPN offer more flexibility than home-router VPN features but require matching settings on the other end. Decide your connection method beforehand. Finally, Amazon listing data can sometimes mismatch the actual product. Confirm the image and title show the Grandstream GWN7003. ## FAQ **Q. Does it have Wi-Fi? ** A. No wireless function is listed. Connect a separate access point. **Q. How many PoE devices can it power? ** A. Two, one per PoE output port. Check the manufacturer's total power budget. **Q. Which VPNs are supported? ** A. Built-in IPsec, OpenVPN and others. See the manufacturer's spec for the full list. **Q. What is the SFP port for? ** A. Gigabit fiber links and similar. Modules are usually sold separately and must match the far end. ### Product Disclosure (Amazon) - Manufacturer: Grandstream - Seller: Amazon Global Store - Fulfilled by: Amazon Global Store - ASIN: B0CD5C3RT3 - Note: This article covers a manufacturer-made product based on Amazon listing details.
