Grandstream GWN7003 Multi-WAN VPN Router with 9 GbE and 2 SFP

The Grandstream GWN7003 is a wired head-office router with nine Gigabit ports and two 2.5G SFP ports, supporting up to 100 VPN tunnels and 60,000 NAT sessions. It is built for companies linking several branches and managing up to 150 access points from one rack.

====

The Grandstream GWN7003 is the largest wired router in the GWN700x line, and it belongs in a head-office rack. It brings nine Gigabit ports and two 2.5G SFP ports, handles up to 100 concurrent VPN tunnels and manages up to 150 Grandstream access points. For a company tying together several branches, or running Wi-Fi across a multi-floor building, it puts routing, site links and Wi-Fi control in one unit.

Grandstream GWN7003 key specifications

Figures from the official GWN700x user manual:

• 9 Gigabit ports and 2x 2.5G SFP, every port WAN/LAN configurable.
• 2.2 Gbps NAT routing and up to 530 Mbps IPsec VPN.
• Up to 100 VPN tunnels and 60,000 NAT sessions.
• 32 VLANs and 64 DHCP servers.
• 512 MB RAM on a 1 GHz dual-core CPU.

Branch links and remote access

A hundred simultaneous tunnels means head office can take in its Jeddah, Dammam and Makkah branches plus staff working from home, all on one router. It supports IPsec site-to-site and client-to-site, OpenVPN server and client, WireGuard, L2TP and PPTP. Larger networks get OSPF, RIP and BGP dynamic routing, alongside static and policy routes for steering a specific system onto a chosen line.

Multi-WAN and network segmentation

With nine configurable ports plus two SFP, assign what you need to STC, Mobily and Zain lines and leave the rest for devices. Thirty-two VLANs and 64 DHCP servers let you keep staff, guests, cameras and phones on separate networks with their own address ranges. QoS puts VoIP calls first and shows bandwidth use per application. Hardware acceleration is available for maximum speed, but the manual notes it switches off QoS, rate limits, statistics and content security.

Wi-Fi controller and rack mounting

The embedded controller runs up to 150 GWN access points, enough for a hotel, school or large warehouse without a separate controller, with cloud management through GDMS Networking. Two PoE output ports offer up to a 36 W budget with the 24V 2A adapter supplied on hardware revision V2.0 and later.

Two brackets, eight screws and a ground wire come in the box for 19-inch rack or wall installation.

Typical Saudi deployments

• A company with branches across the Kingdom that needs always-on VPN tunnels.
• A hotel in Makkah or Madinah running dozens of access points on every floor.
• A logistics warehouse separating scanner traffic from office traffic with VLANs.

GWN7003 or GWN7002?

Performance is the same on both: 2.2 Gbps routing, 530 Mbps VPN, two SFP ports and two PoE outputs. The GWN7003 adds five more Gigabit ports (nine versus four), 512 MB RAM instead of 256 MB, 60K NAT sessions, 100 VPN tunnels instead of 50, 150 managed APs instead of 100 and 32 VLANs instead of 16, plus rack mounting. The smaller GWN7002 is the better fit for a branch or small office.

Frequently Asked Questions

How many branches can the GWN7003 connect?

It supports up to 100 concurrent VPN tunnels, shared between branch links and remote users, at up to 530 Mbps IPsec.

Is it rack-mountable?

Yes. Two brackets, eight screws and a ground wire are included for a 19-inch rack. It can also go on a wall or desk.

Do I need a separate Wi-Fi controller?

No. The built-in controller manages up to 150 Grandstream GWN access points.
