Hi Community, my first post here, hoping somebody may be able to advise...
I live on a farm which is too far for broadband but fortunately I also have an office in a nearby town and because I have line of sight I have setup a wireless bridge, this gives me 8 MBits which is wonderful. Some of my equipment, for example a NAS is on the farm, and I need to access them from the office via the wireless link and I occasinally use vnc to access my office desktop from the farm. This all works beautifully.
Ok. now I want to share my internet with my neighbor on the farm, who, in a strange twist also rents an office next to mine downtown, so I would like to give him access to the internet and to his equipment he has there too.. but I don't want him to be able to access my equipment and visa versa I don't want to see his stuff...
This sounds like a job for port based VLAN.. and so what I bought is two Linksys/Cisco SLM2005 layer2 switches in the hope that this would allow me to do what I want... but I'm not so sure now. In the office I use a draytek v2910 which has a vlan feature that allows me to separate the ports from each other, only giving them internet access.
So... if I connect these two switches to each other, and I create a VLAN with the same id on each of the switches, will the corresponding vlans be shared, so, if you assume the following hardware setup:
farm: slm2005 switch
port 1 -> wireless bridge to office: member of vlan "2", "3"
port 2 -> access point A for neighbor: member of vlan "2"
port 3 -> my own access point B: member of vlan "3"
office: slm2005 switch
port 1 -> wireless bridge to farm: member of vlan "2", "3"
port 2 -> access point C for neighbor: member of vlan "2"
port 3 -> my access point for office D: member of vlan "3"
port 4 -> router port 1: member of vlan "2"
port 5 -> router port 2: member of vlan "3"
the router (draytek v2910) is configured in such a way to separate port 1 and port 2 (otherwise there would be a loop...)
The idea here is to create a vlan "2" for my neighbor and "3" for myself. but what's the correct way to consider the wireless bridge inbeetween (in fact, I think the same problem would occur if I just connected the two switches with a cable (if i had a 2 mile long one..)...)
Will my neighbor be able to see both access points "A" and "C" and the internet, but not be my access points "B" and "D"? Or does this whole concept of VLAN over bridge not work like this, or not at all?
Re: vlan over wireless bridge with internet sharing?
its a Repeatit bridge, a pair of SU-5410a to be exact. it creates a bridge using 802.11a and works fine over 2 miles.
my worry is that I might create a loop with connecting two of the ports of the SLM2005 to the Draytek Vigor 2910 router. However, I think it will work if I use the built-in "VLAN" capability of the draytek (not compatible with any standard protocol): The router allows me to isolate ports from each other, so I think there is no loop.
I guess, coming from the primitive (but functional) Draytek I wasn't sure whether the VLANs on the Linksys/Cisco switches work even on separate switches... but it sounds like they do..
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
