Hello Experts,

I think I have a fairly unique situation that I would like to find the best solution for.

I have an office network made up of desktop and laptop computers that connect to a single wireless router (either via wired or wireless ethernet) and am using a cable modem for internet connectivity.

I also have an enclosed trailer that I work out of at remote sites.  It will also have desktop and laptop computers networked via wired and wireless router.  When I'm mobile, I will use the wifi hotspot on my Droid X to get internet for my work trailer.  My main desktop computer in the trailer will have both a wired ethernet card (connected to the router so it can talk to other computers), and I will also be putting a wireless network card in it so I can also connect to my Droid when needed and get internet.

I have created a diagram of what I'm trying to do if it will help describe things better than I can with words:


What I want to be able to do is when my trailer is parked at my office, I want the two routers to be able to "bridge" together so that I can transfer files to and from the trailer and the office.  I also want to be able to get on the internet in the trailer without having to get out my phone (i.e. when trailer is at the office, I would like for the computers in the trailer to be able to access the internet via the cable modem in the office).

I have a couple of wireless routers that I can use now, but I don't think they will do what I want to do.  I am willing to buy whatever I need to buy to make this setup happen.

When the trailer is not at the office, these two will obviously operate completely independent of one another.  I'm assuming each router will need to be able to handle DHCP requests independently, and each will have it's own subnet.  But when they come together, I want them to "bridge" together so they act like one big network.

Is this doable?  If so how and what do I need to buy to make it happen?
