FAQ
- Which Left 4 Dead 2 server-admin tools are available?
- We list 4 tools for Left 4 Dead 2: Preserving server.cfg editor, Permissions and multiplayer checks, Install, launch and ports, Map and content manifest audit. All of them run straight in your browser.
- Which ports does Left 4 Dead 2 need open?
- UDP27015 defaults to game and A2S traffic. Optional TCP27015 is RCON: configure your own password and restrict trusted sources. Client port 27005 is not a required inbound server port. Check actual -port, NAT and lobby reservations; a query does not prove map or plugin compatibility.
