LAN multiplayer behind NAT is not working?

[icallmyselfi]

What does "Lan" mode means?

We are unable to host a game inside lan.
My friend and I both have a steam version with Heart of Gold DLC.
Both of us stay inside same lan segment (192.168.0.*) beyond NAT which we cant manage.
Firewalls are disabled.

I think it would be good to implement game search using simple UDP broadcast in LAN mode or at least "Invite to game" steam menu.

LAN means Local Area Network. Unless you are both using the same network, LAN is not going to work for you, regardless if you both have steam or not.

Hi Icallmyselfi

Nice to see another networking professional (or at least someone who has knowledge!), I used to work as a network engineer for a county council in the UK :)

Thanks for the heads up on this. When I'm next in the office on Monday I'll organise a test to see if we see the same thing (We didn't see it in our last test, but maybe something changes in the latest patch)

In the meantime would you be able to chuck us a bug report on our tracker (There's a stickied link in the forums, sorry I'm on a phone right now). Include as many details as you can.

Cheers,

Lee

Unless, of course they use a VLAN like Tunngle or Hamachi.

Thank you. Some time ago I have finished CCNP track. ;)
So I could gather any related info you desire (including Wireshark log).

For some reason I have to ask if you disabled IPV6, while playing, as it and its windows associated software spams the network.

The open system interconnectivity model is a good one to keep in mind and has saved many grey hairs.

I noticed there is an invite to game in the game within the multiplayer setup.
But this could be new.

Invite only, not public and not password.

Isnt the C band 192.168.1.X

[icallmyselfi]

Exactly. "192.168.1.X/24" is a class C subnet for local networking.
And there is a Router with NAT towards internet. But I have no access to it.
