Port Requirements and Firewall Configuration
All ports required for Conan Exiles dedicated server operation, including game, query, raw UDP, and RCON.
Required Ports
Conan Exiles dedicated servers require the following ports to be open and correctly mapped:
| Port | Protocol | Purpose |
|---|---|---|
| 7777 | UDP | Game traffic (client connections) |
| 7778 | UDP | Raw UDP (required alongside game port) |
| 27015 | UDP | Steam server browser query |
| 25575 | TCP | RCON (optional, only if RCON is enabled) |
All four ports must be opened on the host firewall. If you are behind NAT, they must also be forwarded to the server's internal IP.
Port Allocation in Panel
In WISP or Pterodactyl, ports are allocated per-server. You must allocate all required ports and map them correctly in your startup variables:
- Primary allocation:
7777(this becomes the server's main port) - Additional allocations:
7778,27015,25575
In the server startup parameters, reference the panel's port variables:
-Port={{SERVER_PORT}} -QueryPort={{QUERY_PORT}} -RconPort=25575
Replace {{SERVER_PORT}} and {{QUERY_PORT}} with the actual variable names from your egg configuration.
Engine.ini Port Settings
Confirm the ports match your panel allocations in Engine.ini:
[URL]
Port=7777
[OnlineSubsystemSteam]
ServerQueryPort=27015
If you use non-default ports (e.g., due to hosting multiple servers on one node), update both the INI and the panel port mappings to match.
Why Port 7778?
Port 7778 (UDP) is the raw UDP port used by the Unreal Engine networking layer alongside the main game port 7777. It is automatically used and does not need to be explicitly configured — it simply must be open. Many firewall setups block it because it is not documented in the Steam app listing. If clients can connect but experience high packet loss or desync, verify that 7778 UDP is open.
Host Firewall (Linux)
If the node is running ufw or iptables directly, ensure the rules are in place:
ufw allow 7777/udp
ufw allow 7778/udp
ufw allow 27015/udp
ufw allow 25575/tcp
For iptables directly:
iptables -A INPUT -p udp --dport 7777 -j ACCEPT
iptables -A INPUT -p udp --dport 7778 -j ACCEPT
iptables -A INPUT -p udp --dport 27015 -j ACCEPT
iptables -A INPUT -p tcp --dport 25575 -j ACCEPT
Multiple Servers on One Node
When running multiple Conan Exiles instances on a single node, each server needs its own unique set of all four ports. Increment by a consistent offset, for example:
Server 1: 7777 / 7778 / 27015 / 25575
Server 2: 7779 / 7780 / 27016 / 25576
Update both Engine.ini and Game.ini on each instance to reflect its assigned ports.
