Download Server File

I currently run an 2 unturned servers with friends but want to swap our old ones out for new maps. Is there a way to download the world and keep it or to add more tunnels, as it says the max is 4. Any help appreciated

if you dont run them at the same time you can just use the same tunnels
you would just need to setup another server (you can use steamcmd for that)

if you want to run them at the same time you would need to use more tunnels
2 tcp+udp tunnels per server
(i think you can do this with the default tunnel cap)

So another server with the same address would work ok?
