Rent Vietnam VPS for Access Facebook from China Location

BM BizMaC Team Jul 21, 2026 10 min read

The Great Firewall of China (GFW) blocks Facebook, Instagram, WhatsApp, and Messenger entirely. If you are a business traveler, an expatriate, or a remote worker based in China and need to access these services, the most reliable solution is to rent a Vietnam VPS for access Facebook from China location. A VPS physically located in Vietnam offers low latency to China, a clean dedicated IPv4 address that is not blacklisted, and full root control to set up your own encrypted tunnel. This guide walks you through exactly how to pick the right provider, set up WireGuard on Ubuntu 24.04, and keep your connection stable under GFW conditions.

Why a Vietnam VPS Works Better Than Alternatives for China Facebook Access

Consumer VPN services have a terrible track record in China. Their IP ranges are well-known, ports are identified by deep packet inspection (DPI), and the GFW blocks them within hours or days. A Vietnam VPS with dedicated IPv4 solves this because you control the IP, the port, and the protocol. Vietnam is geographically close to southern China, latency from a Hanoi or Ho Chi Minh City datacenter to Guangzhou or Shanghai is under 40 ms, so the connection feels fast even through encrypted tunnels. The clean IPv4 address has never been used for VPN traffic, so it starts with a clean reputation. You can also change the listening port and protocol if the GFW starts throttling it, which you cannot do with a commercial VPN.

What You Need Before You Start

  • A VPS located in Vietnam with a dedicated IPv4 address and full root access. We recommend a 2 GB RAM, 1 vCPU plan on NVMe storage for smooth WireGuard performance.
  • Ubuntu 24.04 LTS installed on the VPS (Debian 12 and AlmaLinux 9 also work with adjusted commands).
  • A non-root sudo user on the VPS.
  • The WireGuard client installed on your local device (Windows, macOS, Linux, Android, or iOS).
  • An understanding that the GFW actively probes for VPN traffic, we will show you how to harden your tunnel.

If you need to rent a VPS in Vietnam for this purpose, make sure the plan includes at least one dedicated IPv4 and full root access so you can install any VPN software.

Step 1, Choose the Right Vietnam VPS Provider

Not every VPS provider in Vietnam is suitable for accessing Facebook from China. You need a provider that offers:

  • Dedicated IPv4, shared or NAT IPv4 will get you blocked quickly because other users' traffic pollutes the IP reputation.
  • NVMe SSD storage, small packet overhead from WireGuard benefits from low I/O latency.
  • No bandwidth restrictions on international traffic, some Vietnam providers throttle cross-border bandwidth.
  • Monthly billing and no long-term contract, if the IP gets blocked, you want the freedom to terminate and spin up a new one without penalty.

A Linux VPS from a Vietnam-based provider like BizMaC (thueVPS) gives you those exact features: dedicated IPv4, full root, NVMe storage, and you can reinstall the OS or take a snapshot before making major changes. The pricing starts from around 189,000 VND per month (roughly $7.50 USD), which is competitive for a clean Vietnam IP.

Step 2, Initial Server Setup and Firewall

Log in to your VPS via SSH:

ssh youruser@your_vps_ip

Update the system and install the WireGuard package:

sudo apt update && sudo apt upgrade -y
sudo apt install wireguard -y

Configure the firewall to allow only SSH and the WireGuard UDP port. We will use port 51820 initially, but you can change it later if the GFW starts probing:

sudo ufw allow OpenSSH
sudo ufw allow 51820/udp
sudo ufw enable

Verify the firewall rules:

sudo ufw status numbered

You should see both rules active. Now enable IP forwarding so the VPS can route traffic for your client:

sudo sysctl -w net.ipv4.ip_forward=1
echo "net.ipv4.ip_forward=1" | sudo tee -a /etc/sysctl.conf

Step 3, Configure the WireGuard Server

Generate the server private and public keys:

cd /etc/wireguard
umask 077
wg genkey | tee server.key | wg pubkey > server.pub

Create the server configuration file /etc/wireguard/wg0.conf:

[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = <contents of server.key>
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

[Peer]
PublicKey = <client_public_key>
AllowedIPs = 10.0.0.2/32

Replace eth0 with your actual public network interface (check with ip route show default). The PostUp and PostDown lines handle NAT masquerading so your client can access the internet through the VPS. Leave the [Peer] section with a placeholder for now, you will fill in the client key after generating it on your local machine.

Enable and start the WireGuard service:

sudo systemctl enable wg-quick@wg0
sudo systemctl start wg-quick@wg0

Check that the interface is up:

sudo wg show

You should see the interface with the peer you added (the client will show as not yet connected).

Step 4, Configure the WireGuard Client (Your Local Machine)

Install WireGuard on your local device. On Linux:

sudo apt install wireguard -y

On Windows or macOS, download the official WireGuard app from wireguard.com. Generate a key pair on your client:

wg genkey | tee client.key | wg pubkey > client.pub

Create the client configuration file (e.g., wg-client.conf or import it into the WireGuard app):

[Interface]
PrivateKey = <contents of client.key>
Address = 10.0.0.2/24
DNS = 1.1.1.1

[Peer]
PublicKey = <contents of server.pub>
Endpoint = your_vps_ip:51820
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 25

Set AllowedIPs = 0.0.0.0/0 to route all traffic through the VPS (this is necessary for Facebook access from China). The PersistentKeepalive at 25 seconds helps maintain the connection through NAT and over unstable networks.

Now copy the client public key back to the server and add it as a peer. Edit the server's wg0.conf and set the [Peer] section:

[Peer]
PublicKey = <client_public_key>
AllowedIPs = 10.0.0.2/32

Restart WireGuard on the server:

sudo systemctl restart wg-quick@wg0

Activate the client connection. On Linux:

sudo wg-quick up wg-client.conf

On mobile, scan the QR code generated by qrencode -t ansiutf8 < wg-client.conf (install qrencode first).

Verify the Tunnel and Test Facebook Access

Check that the handshake completed on both sides:

sudo wg show

You should see a recent handshake time (seconds ago). Now test your IP from within China:

curl ifconfig.me

It should return the VPS's IP address in Vietnam. Then try accessing Facebook:

curl -I https://www.facebook.com

If you get a 200 OK response, the tunnel is working. Open your browser and log into Facebook. If you are inside China, DNS queries for facebook.com may still be blocked, add DNS = 1.1.1.1 or 8.8.8.8 in the client config as already shown above.

Step 5, Keep the Tunnel Alive Under GFW Conditions

The GFW actively probes for WireGuard traffic by looking for UDP packets on known ports and by attempting to initiate handshakes. After a few days or weeks, your VPS IP may start being throttled or blocked. Here is how to extend its life:

  • Change the listening port every 2 weeks. Edit ListenPort in the server config and update the Endpoint in the client config. Use a port above 50000 (e.g., 54321), less likely to be probed.
  • Switch to a TCP-based wrapper. WireGuard is UDP-only, but you can wrap it with udp2raw or socat to tunnel it over TCP. This adds overhead but makes DPI harder.
  • Use a non-standard MTU. Set MTU = 1280 in both the server and client [Interface] section. The GFW sometimes drops packets that match standard MTU sizes.
  • Set up monitoring. Use a simple cron job to ping Facebook every 5 minutes and send an alert if the tunnel drops. If the IP gets fully blocked, spin up a new VPS with a fresh IP.

Because you are renting a VPS in Vietnam with a dedicated IPv4, you can simply reinstall the OS on the same VPS to get a fresh IP from some providers, or terminate and create a new instance. With thueVPS, you can reinstall the OS through the control panel in under a minute, and the new instance gets a different IP from the pool.

Troubleshooting Common Issues

Handshake fails or never completes. Check that UDP port 51820 is open in the VPS firewall and that the ISP in China is not blocking UDP entirely. Some Chinese mobile networks (China Mobile, China Unicom) block UDP on certain ports, try switching to TCP via udp2raw.

Facebook loads but very slowly. Latency from Vietnam to China is normally low, but if the GFW is throttling your IP, every packet is delayed. Run a ping test:

ping -c 10 8.8.8.8

If ping times are above 200 ms, the VPS provider's international bandwidth may be congested. Choose a provider like thueVPS that uses Tier 3 datacenters (Viettel IDC) with domestic bandwidth to China.

Connection drops every few minutes. Increase PersistentKeepalive to 20 seconds. If the problem persists, the GFW may be sending RST packets to tear down idle tunnels, switch the port and try again.

FAQ

What if my VPS IP gets blocked by the GFW?

Terminate the instance and create a new one with a fresh IP. Many providers, including thueVPS, assign a new IPv4 automatically when you reinstall the OS or create a new VPS. Keep your WireGuard config ready so you can redeploy in minutes.

Can I use OpenVPN instead of WireGuard for Facebook access from China?

Yes, but WireGuard is strongly preferred in China because it uses a single UDP port and produces fewer identifiable patterns. OpenVPN over TCP is easily recognized by DPI and gets blocked faster. If you must use OpenVPN, run it over port 443 with TLS encryption (obfuscation) to mimic HTTPS traffic.

Do I need a VPS with multiple IPv4 addresses?

No. One dedicated IPv4 is sufficient. Multiple IPs add no benefit against the GFW, it blocks the IP itself, not the service. A single clean IP and a willingness to rotate it when blocked is the best strategy.

How much bandwidth do I need for Facebook usage?

Typical social media browsing uses 100, 200 MB per hour. For light use (messaging, scrolling news feed), a 1 TB monthly plan is more than enough. A 2 GB RAM, 1 vCPU VPS with 1 TB bandwidth costs around $7.50/month from thueVPS.

Can I run the tunnel from a shared hosting account instead of a VPS?

No. Shared hosting does not give you root access, cannot install kernel modules like WireGuard, and its IPs are shared with hundreds of users, they are already blacklisted. You need full root access on a dedicated IPv4 to build your own tunnel.
