I have two design questions that I would like to get answered if at all possible. I don't need config help but just an understanding of how this is accomplished.
In an enterprise network that consists of direct internet access at the corporate or main location with multiple branch offices and remote locations whose traffic has to come back to corporate before going to the internet, how is layer 2 trunking and VLANs supported?
How do I get a vlan at the corporate office to reside at a branch location while traversing several routers over L3? Say I needed one port on a switch at the branch office to be the 'Public' VLAN because they wanted to place a public facing server there. Or, I wanted to extend a management VLAN across the entire network. How is this accomplished across the routers?
This brings me to my next question on NAT. Please refer to the diagram. I have a firewall that NAT's traffic for public servers residing on the inside interface. Say I have a private WAN that connects a remote location that is accessible from internally only? How would I NAT a public address to a server that doesn't reside on the inside network? Is it possible?
Thanks for your help!
