LAN gaming setup, wired and wireless. Game session not visible.

[Michael_sz]

Trying to setup a LAN gaming session for “Anno 1404 Venice”... I had it working in the past with direct Ethernet connections but we have since added an Ethernet-less laptop and therefore using wi-fi. When either machine hosts, the other cannot see the game in the lobby.

Machines:
Wireless router/switch and modem: Hiltron CGN2-ROG
Device1: Windows 7 machine connected directly with Ethernet
Device2: Windows 10 machine connected via wi-fi (no Ethernet port)

Configurations:
-firewalls and antiviruses turned off for all machines including router
-Home Network, HomeGroup: Joined, Connections: Local Area Connection.

Observed behavior:
1. Both computers are on the same sub-net and can ping each other.
2.Can share files through the home group.

3. When launching the game and attempting to host/join games: From Client machine appears to properly broadcast and get a response from the host machine. However this game session does not appear in the in-game join screen, just empty. No further network communication appears to occur.

wireshark:
Source:192.168.0.16 Dest: 192.168.0.15 Protocol:UDP
INFO: 9100 → 9100 Len=272
Source:192.168.0.16 Dest: 192.168.0.15 Protocol: UDP
INFO: 9100 → 9100 Len=272
cmd:
\Users\Michael>netstat -na | find "9100"
UDP 0.0.0.0:9100 *:*

If any more details are needed I would be happy to provide.
Any suggestions or fixes would be greatly appreciated,

Michael

UPDATE:So I just picked up a DLINK DIR-819, set up the LAN the same way and everything worked fine. So indeed seemed to be an issue with the Hiltron router.

I only investigated the IPs... if the MAC addresses were wrong how would I go about correcting that?

If you could get no access between them I would be blaming a feature called wireless isolation but because you can ping it means they can communicate. Even if you wanted to there is no way to filter traffic between the machines. All traffic is allowed.

Maybe a bug in the firmware of the router. I would run wireshark on both machine at the same time and see if data is being sent and not received. Look at the mac addresses on the packets to be sure it actually has the proper address. The wireless and lan ports are should appear as a single bridged network.
