Ok .. so i had some servers on dynamic ip addresses , natted thru firewalls  etc.

and they worked FINE ,showing up in all the RUST server lists and everything, usually within 1 minute.

After moving to a fixed ip address, clients can connect, but the servers don't show in the lists.
also the ip addresses are not blacklisted in thier blacklist.

I've natted ,filtered ,reverse-natted, re-directed, massaged, UDP'd, and TCP'd  this shit to within an inch of its life...
But still no show in the lists.

28015 & 28016  maybe 28082 are the only ports i think there are.
Ping works to the server via the external address  (by that i mean u turn the machine off & ping fails)

oh and ws://address:28082  shows as connected when tested.....

Rust uses Steam server browser, and support refuses to give answers on how it works. But usually it depends on the region, if at least one person sees it then it is OK. What is your server IP and your country where you are querying servers from?

Spent a couple of days on this...... with some high end networking kit
found out some real interesting things....
no wonder they don't want it public....
Also had one of the big firewall manufacturers looking into it as well..,  That was a W*F from some of their hardware engineers...

1. there is a LOT of Russian traffic, looks in some cases they are using  RUST as a DDos server, either that or 80% of the traffic is from russian bases...
2.Even if a client can connect, or multiple clients, that is no gurantee the  Battle metrics or even the steam servers can see it.
infact you can hide in plain sight... even the rust client is telling  steam the details... and Battle metrics CAN see the Rcon oport....
3.It's possible to "spoof existing servers" grab users also maybe connects.., even if you are a 3rd party...
I'd previosuly reported to steam/FP i had seen logins being hijacked,.. now i think i know how it can be done.
4. a clear understanding of WHY people cannot get THEIR servers to show up....

Anyway after this it is now fixed ... but... wow... just wow..

That's all very clever, shows us what a powerful technician you are and it's nice to know that you fixed it for YOURSELF, but the info is useless to anyone else wanting to know how to get their server listed. Why don't you provide this info instead of just congratulating yourself?

Becasue if i did......... it gives the info for all sorts of chaos on the system....
and it won't solve thier conenction problems becasue it is the ISP doing it.
It would give every script kiddy a pointer of how to implement a DDos against servers & users, using themselves.

What it does is give the relevent people a pointer of where to look... FP & Steam seem disiteresed.
Looks like they recently rolled back the patch on respawn, where it "reconnected" to validate the users...

I'm more intersted in whats going on in Russia..
