Network and Firewall Issues

Port Configuration

# Default Abiotic Factor server ports
Primary Game Port:     7777  (UDP)  # Game traffic
Query Port:           7778  (UDP)  # Server browser
RCON Port:            7779  (TCP)  # Remote administration
Backup Port:          7780  (TCP)  # Backup transfers (if configured)

# Firewall configuration examples
# Windows Firewall:
netsh advfirewall firewall add rule name="Abiotic Factor Game" dir=in action=allow protocol=UDP localport=7777
netsh advfirewall firewall add rule name="Abiotic Factor Query" dir=in action=allow protocol=UDP localport=7778
netsh advfirewall firewall add rule name="Abiotic Factor RCON" dir=in action=allow protocol=TCP localport=7779

# Linux iptables:
iptables -A INPUT -p udp --dport 7777 -j ACCEPT
iptables -A INPUT -p udp --dport 7778 -j ACCEPT
iptables -A INPUT -p tcp --dport 7779 -j ACCEPT
iptables -A INPUT -p tcp --dport 7780 -j ACCEPT

# Router port forwarding:
# Forward external ports 7777-7780 to server internal IP
# Example: 192.168.1.100 internal, forward to that IP

REM Test port accessibility locally
echo Testing local port 7777...
netstat -an | findstr ":7777"
if errorlevel 1 echo ⚠ Port 7777 not listening locally

REM Test external accessibility (requires external tool or second machine)

echo External connectivity tests:
echo 1. From player perspective: telnet YOUR_EXTERNAL_IP 7777
echo 2. Port check website: https://www.yougetsignal.com/tools/open-ports/
echo 3. ISP verification: Contact ISP about UDP port restrictions

Log Analysis

Understanding Server Logs

# Common log locations
Windows:   AbioticFactor\Saved\Logs\
Linux:     ~/AbioticFactor/Saved/Logs/

# Important log files
AbioticFactor.log          # Primary server log
AbioticFactor-backup-1.log # Previous log (rotated)
Launch.log                 # Server startup log
Crash.log                  # Crash reports (if any)

# Key log patterns to monitor
ERROR:     # Critical errors requiring immediate attention
WARNING:   # Potential issues that may become problems
Failed:    # Operation failures
Exception: # Software exceptions and crashes
Timeout:   # Network or operation timeouts
Missing:   # Missing files or resources

# Log analysis commands
# Windows: findstr "ERROR" AbioticFactor.log
# Linux: grep "ERROR" AbioticFactor.log

# Real-time log monitoring
# Windows: Get-Content AbioticFactor.log -Wait
# Linux: tail -f AbioticFactor.log
