Good day, I am trying to create an Offline LAN|PVE|RPG server for mr and my brother. The idea is to save data as we cannot affort to play rust anymore, but enjoy playing it too much to just stop. We connect to the same router.

I already have a server and all but it triggers an exception when running the .bat while i have no internet Access. the commandprompt complains about Compiler.exe having a MD5 missmatch and it loos like that occures somewhere around trying to look for updates.

Running the same .bat with internet access seems to work, but when try it offline again it refuses to work. 

I have tried it with and without being connected to the modem and the same happens.

Any advice or instruction will be appreciated.

Why would you make it completely offline? To make the server local simply make it like that by setting IP to 127.0.0.1 or block your rust port usage you know.

@misticos in there first line they put "The idea is to save data as we cannot affort to play rust anymore" as there reason for wanting to make it completly offline. Which I mean if they have metered data that would make sence but I dont think Rust itself is set up for offline play.... I think steam would have a crap fit

I think you'd need internet once to do the install bat (the one with install_dir).

After that, if the clients and the server are all on the right game version, you could host the rust server inside your lan offline.

As I'm thinking about this, I'm not entirely sure. I think so, though.

Alright, I tested: You need internet to get the server set up, but don't to run it. My mods gave a lot of errors, cuz they couldn't connect, but a vanilla build or a lightly modded one would work. The 127.0.0.1 IP would work if it were just you, but that's the localhost IP so that won't work for your LAN party. Set the server ip to something like 192.168.0.200:28015 and have each of the clients do client.connect 192.168.0.200:28015 in the F1 console to connect. Everyone has to be connected to the router.

Yes as Razor said 14150 said:

I was planning on saving data in this manner while playing with my brothers and 3 of our neighbours via a big LAN. I thought that steam would be nice enough to allow me to run my game 100% offline. This logic was similar to Ryan's thinking:

Rust needs to create a Auth ticket to make sure that the game is not cracked. To do that you need to be connected to the internet and run steam online. But ofcourse the problem is with steam, quite apparently they need to make sure the client is not cracked. every. damn. second. of. playing. rust. so losing connection will give you a auth ticket cancelled problem and disconnect you from the server. There after you will not be able to create a new auth ticket as your PC is offline.

So RIP Dreams.
But running rust locally doesn't consume that much data if you make sure everyone is connecting via your local IP. Getting the routers to talk to one another is hell tho.
