Just wondering if this is possible, we have a leased cisco 2911 (That I do not have access to) at that is set up with a site to site VPN to tie into a third party's Active Directory server.
Our other locations is a mix of netgates and site-to-site to the central office, that I would like to replace with our own equipment.
What I am planning to to is put a new router in the central office network and create a new VPN structure with our own routers (either 1921's or 2911's) so I can send VLAN's over the VPN without involving a third party.
I want to make sure I can tie the daughter stores into the third party's Active Directory server though the main store.
I have seen a few site-to-site discussions that were under a NAT but they were the the DHCP server as well, I just want to make sure my plan will work before I order 10 routers.
