Hi,

I'm trying to setup VLAN on a Vigor 2800G.

I want to be able to isolate a PC on my network so that it has internet connectivity but not be able to see any other machines on the local network.

I have connected it to Port 2 and setup that port to be a different VLAN to the rest of the network.

It seems to work mostly (I have internet access and cannot ping machines that I know are there) but using Vista Network browser I can see certain machines that are on the local network.

This seems to vary over time, some come, some go but it is very worrying as I thought that the VLAN was supposed to prevent any traffic going between VLAN0 an VLAN1

Is this a known issue with Vista traffic? So far it's only Vista to Vista connections I can see.

I have upgraded to the latest stable firmware but with no difference.

Any help you can give would be appreciated.

Thanks and best regards,

Andy.

i've had issues similar to this on a 2950 with subnetting. sometimes traffic goes to the router processor and bypasses the switch processor and vlan.
