Bridging two VLAN's together (Steam Local Network Game Transfer)

Hello,

I have a seperate VLAN for every gamer in our household. (for easy management of who is downloading to much, who needs to go to bed, who is beeing punished :) )

So the VLAN's are not realy for security, but more for management especialy since we have a very slow internet connection (only 95Mbps)

All is working great except for one thing, because of the VLAN seperation, the Steam Local Network Game Transfer feature does not work, and this is very usefull for us, since we have only 95Mbps its very nice if only one PC needs to download a game/update and the other PC's can than transfer it from this PC instead of also downloading it.

I figured I can Bridge the Gamers VLAN's for this. (it is ok if they are not seperated anymore from each other, aslong as all the security to the outside stay's the same.

I am no expert and found some guides about bridging multiple VLAN's but I cant seem to get it to work,
Anyone have a "dummy's" step by step guide for me ?

I created the bridge, added the 3 gamers VLAN's to it, enabled it, and than tried adding firewall rules just allowing everything to everything between the VLAN's but it does not seem to work :(


Any tips are appreciated,


Hans

You shouldn't need to bridge the interfaces. If the VLANs are all setup correctly, traffic should be routable so a few firewall policies should be all you need. Check the users Windows firewall is configured, too.

Have a read of the Steam FAQ regarding the requirements:
The network transfer happens on TCP port 27040 and it needs to be allowed by local firewall software. You also need to open UDP ports 27031-27036 for client discovery.


Are you able to add in a network diagram?
