Satisfactory Server Port Forwarding

Satisfactory Server Port Forwarding

Satisfactory uses three ports. All three must be open for the server to be reachable and discoverable.

Required Ports

Ports are set via launch arguments: -Port=7777 -BeaconPort=15000 -ServerQueryPort=15777

UFW (Ubuntu/Debian)

sudo ufw allow 7777/udp
sudo ufw allow 7777/tcp
sudo ufw allow 15000/udp
sudo ufw allow 15777/udp
sudo ufw reload
sudo ufw status

firewalld (RHEL/CentOS/Fedora)

sudo firewall-cmd --permanent --add-port=7777/udp
sudo firewall-cmd --permanent --add-port=7777/tcp
sudo firewall-cmd --permanent --add-port=15000/udp
sudo firewall-cmd --permanent --add-port=15777/udp
sudo firewall-cmd --reload

iptables

sudo iptables -A INPUT -p udp --dport 7777 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 7777 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 15000 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 15777 -j ACCEPT
sudo iptables-save > /etc/iptables/rules.v4

Router / NAT Port Forwarding

If hosting on a home network, forward all required ports to your server's local IP:

Changing Default Ports

Pass custom ports via launch arguments:

./FactoryServer.sh -Port=7778 -BeaconPort=15001 -ServerQueryPort=15778 -log -unattended

Reminder: All port arguments must appear before -log -unattended or they will be silently ignored.

Running Multiple Instances

Each instance needs a unique set of ports:

# Instance 1
./FactoryServer.sh -Port=7777 -BeaconPort=15000 -ServerQueryPort=15777 -log -unattended

# Instance 2 (separate terminal / service)
./FactoryServer.sh -Port=7778 -BeaconPort=15001 -ServerQueryPort=15778 -log -unattended
