I will try and describe the problem as detailed as i can.
As of today we have a main office and a remote office, the remote office is connected to the main office through a Wan connection (Layer 3).
So basically they are connected straight to the switch at our main office and are seen as a local part of the network here in every way.
Now there are a second remote office that are soon to be connected to the main office.
The Wan supplier has now decided that they will change the technology a bit and they are merging Remote office 1 and 2 at their location and adding a Vlan tag to each office.
Remote office 1 vill be tagged "vlan10"
Remote office 2 vill be tagged "vlan11"
So i will get both the remote sites through the same cable but tagged on different vlans to the main office.
I am curious on how to best solve the solution to have a transparent network with full permissions to either network.
The simplest solution would be to have all nets acting as one net with the same ip range, it's small offices so there are maybe 5 users or so.
We have a HP procurve switch 3500yl that are connected to the remote office today and a ASA 5510 firewall for external connections.
I would think that you could trunk a port in the swith, but are unsure on what configurations need to be put into the firewall.
This problem is something that i should be finnished with this week ^^
