    Has anyone been able to make this work? I have set one up and can't get it to work. I don't want to go into great detail unless I know someone can help me.

    What is it that you are trying to do? Just about any switch on the market now adays, from really expensive to really cheap are transparent? What sets them apart are their feature set and ability to build mac address tables.

    Edit - ok took a quick look at what linksys is deeming a transparent bridge option with the RV. Personally i dont see a need, maybe you will have a specific instance that doenst come to mind but to me it appears to be a useless feature.

    We have site that has a main office and a sales office that is located across the parking lot. There is a cable (cat5--less than 100yds) that connects the two. There are RV082s at each location. The main office has a cable modem connect and so does the sales office. The servers are at the main office. I need the sales office to use their own cable modem for internet access and still see the servers at the other location. I have given the sales office router an ip address of 192.168.16.1 and turned on DHCP. I have given the main office an ip address of 192.168.17.1 and turned on DHCP. For now I have created a vpn tunnel between the two routers and the sales office can see the servers. But they are complaining that is is slow. I would prefer to use the wire between the two locations but can't figure out how to make the routers talk to one another.

    Ok now we can have some fun, ok here is a way to make it work. I will continue to give it more thought and see if i can come up with something else.

    Main office
    192.168.17.1
    Dhcp enabled

    Sales office
    192.168.17.x (an ip within the 17 network range you are not currently using)
    Dhcp disabled

    Take the copper line you have between the 2 buildings and connect them via a lan port on both routers. You can statically assign ip's to all machines in the sales office giving them the ip of the sales router as their default gateway. Setting it up this way you can still access the servers in the main office and have the hosts in the sales office use the sales router for internet access. Will also give you the option of leaving dhcp enabled on whatever hosts you choose too, but know they will pull dhcp from the main office router and use it for internet access.

    Ok here is another option that just came to mind, but you will have to tell me if this is an option.

    keep the setup exactly the same as you have it now, take the copper run and connect it to wan2 of the sales office to a lan port of the main office. Tell wan2 to pull its ip via dhcp (its going to get a 192.168.17.x ip). You should not have to set any static routes or do anything else to make it work, though you will have to connect to the servers via ip and not name. Now this is thinking that the RV series is going to route traffic as it should and send all 17.x traffic out wan2 only since its directly connected to that network. I have also heard there is a way on the RV series to link certain traffic to one wan port of the other, but i have also heard there has been some issue with that. Just another possible option.

    Good and you gave me options as well. I like the second one. The site is 10hrs away and this one might be the easiest to do remotely. If you think of anything else post it. I have another site to do very similar to this one. Thanks.

    The second option doesn't work. WAN2 in sales does not get an ip address from the main router. I even tried giving it a static ip but it still would not talk to the other router.

    Sounds like potentially the cable run you have in place is either bad or to long? Do you have a way to test it, or in this case have someone test it for you?

    I tend to agree with you. The cable worked before I installed the second router. I tried this set up here and it works. I have noticed the vpn is dropping too. I am wondering if I have a bad router.

    Generally when a device goes bad it just goes bad. Granted in rare instances they just do goofy things but most often when its time is up no matter how long or short it goes belly up. Though that does not take into consideration, heat, lightning or any other external forces that might have or be acting on the unit.
