A router that supports NAT loopback will still check forwarding rules, notice that it goes to your server and "turn the packet around" to your server. A router that doesn't support NAT loopback will simply drop the packet, meaning the request to join will never reach your gameserver. + +To work around this you can set `ns_auth_allow_insecure 1` on the gameserver in the `autoexec_ns_server.cfg`. This way you can directly connect to your server via `connect <local gameserver ip>:<port>` (e.g. `connect 192.168.123.456:37015`). + +Note that this still won't allow you to join your server via serverbrowser. You will always have to use the `connect` command to join it. Also, setting `ns_auth_allow_insecure 1` means that anyone that knows the server IP can join it without authenticating with masterserver, meaning that they can impersonate any player on your server. \ +To resolve this you will have to invest into a router that supports NAT loopback or host your gameserver outside your local network. |
