Terraria is an action-adventure game that puts the player in the middle of the action, requiring them to jump over obstacles and shoot enemies. Adventure games are usually story-driven, with you often playing as the main character uncovering new plot elements as you progress through the game.
If you want to have the best gaming experience while playing Terraria, you need to forward some ports to your router. This strengthens and stabilizes your network connection and can even make it faster. Routers are not typically designed to allow incoming connection requests. However, forwarding a port can positively affect the gaming experience for users.
Why You Need to Port Forward for Terraria
Terraria servers use TCP port 7777 by default. When your server is behind a NAT router, incoming traffic from the internet is blocked unless port 7777 is forwarded. Without it:
- External players can’t discover or join your server
- Host may show up offline or unresponsive
- Multiplayer gameplay becomes limited to LAN only
As documented by the Terraria fandom wiki: “The server runs on TCP port 7777 by default. If you are behind NAT… the port must be port‑forwarded for other players to join”
Terraria Port Overview
| Setting | Value |
|---|---|
| Default port | 7777 TCP |
| Protocols | TCP only (no UDP required) |
| Alternate ports (Steam/TShock) | Additional ports may apply |
| Static IP suggestion | Internal IP of the host (e.g. 192.168.1.50) |
Steam servers or TShock setups may require additional ranges (e.g. Steam uses UDP 27015 etc.), but for standard Terraria standalone hosting, only TCP 7777 is needed.

| TCP Port: | 7777 |
How to open ports behind CGNAT
What if your ISP performs CGNAT? Most ISPs perform CGNAT (Carrier-grade Network Address Translation) to conserve bandwidth and assign a single IP address to multiple users connected to the same internet network. However, CGNAT makes it difficult for you to open ports on the router.
To get around the CGNAT issue, you can use the Port Forwarding add-on to bypass this problem and port forward routers without hassle.
Here’s more information on how to use PureVPN’s Port Forwarding add-on and bypass CGNAT in a few clicks.

Assign your server PC a static LAN IP, log in to your router, go to port forwarding, and forward TCP port 7777 from the WAN to your host’s IP. Save and reboot your router, launch Terraria server, and share your public IP and port. Use external testers to validate connectivity. If you can’t forward via your ISP due to CGNAT, consider VPN-based forwarding.
Port forwarding is a common practice in gaming that makes your console or PC easy to access for other players on the internet. By opening up ports, you can enjoy improved connection speed, shorter wait times for joining games, and smoother gameplay, especially if you’re hosting a game.
To connect and play with other players in multiplayer games, some games require to port forward while other games will try to make the connection automatically; however, this method often fails when one of the players doesn’t have a port forward.
Although port forwarding improves gaming performance, it also creates a security vulnerability as outsiders can access the computer or network. Gamers should only use this service for the servers they trust and ensure their firewall blocks any other incoming connections.
