I know there are a few people around here who know more on these things than me, so your advice would be most welcome please! We've got a site with a Plusnet connection (currently ADSL, but will be placing an order for Fibre soon). We've got a Windows Server 2008R2 acting as domain controller, file server, DNS Server, DHCP Server and VPN Gateway (for a few people to access the network from home on).
We've got another site which until recently was connected by Wifi over a 150metre distance to the first site, which has got a Windows Server 2008 (not R2), which was acting as a backup to domain controller, and stored backups taken from the server on the first site. That link is now broken, and is not possible to be restored (big line of trees in the way that can not be trimmed).
My plan is to get a line installed at this second site with a fibre connection.
So far I'm well within my comfort zone! What I'll then want to do is establish a permanent VPN connection between the 2 sites. I'm guessing the best way for that is to do that directly from the router. If so my first question is if anyone has any suggestions for a decent (fibre) router that could do that? This will be transferring quite a lot of data in the overnight backup.
Next I'm more just after confirmation that if I did this then I would need to have a DHCP server on the second site?
Would the Domain Controllers and DNS Servers still be able to keep themselves in sync across the VPN connection?
Would the VPN Server running on the Window Server at the first site be able to get us access to both sites, or would we need to set up the other Window Server as a VPN Server as well and connect to each site individually?
Just in case anyone was going to make the point, both connections will be with Plusnet Business accounts.
Any recommendations on hardware, or answers to any of these would be most welcome!
Many thanks
Phil

DHCP - you'd probably need a server at each site. DHCP works by local broadcast, so unless your VPN routers support some sort of DHCP helper function a DHCP request from one site isn't going to be seen by the other site.
DNS, Domain traffic and VPN remote access should be able to route between the two sites once the site-to-site VPN is in place.

The Draytek 2800 series will support IPsec VPN tunnels, I use a pair of 2820's to provide a VPN link to a client site. The 2860 also supports VDSL but is not cheap at ~£180. We also have a Fritzbox 7390 in our Netherlands office but again that's >£200, that gives us a VPN tunnel to our UK firewall which is a Smoothwall based box. The TP Link TD-W8980 & 9980 also support VPN tunnels and are good value at around £70 but I have no experience on their performance , the newer TP Link ones such as the Archer VR200 also support VPN and maybe worth a look.
Quote I'm guessing the best way for that is to do that directly from the router. If so my first question is if anyone has any suggestions for a decent (fibre) router that could do that?
Hope that gives at least some food for though...

yes I know you would need a modem on the end of each line (so make that 4 modems) and have them setup as one way traffic systems (one side going out one side coming in) and it might be more expensive in the hardware side but a lot cheaper in terms of installing a secondary line and then monthly rentals.
obviously knowing nothing about the location the question might be redundant but possibly another option to think of /

I don't think DD_WRT supports combined modem/routers so you would need to use the BT modem ( but they're not being supplied after Jan 2016 )

If you don't need wifi ( or have a separate access point ) then, on paper, that looks pretty good. The claimed VPN throughput is 80Mbps. http://www.tp-link.com/en/products/details/cat-4909_TL-ER6020.html#specifications
Quote Someone else has just suggested the TP Link TL-ER6020 to me as well.
However, your maximum VPN throughput is going to be limited by the upload speed on your Fibre ( max 20Mbps ) so might be worth looking at the TL-R600VPN http://www.tplink.com/ir/products/details/cat-4909_TL-R600VPN.html#specifications which has a claimed throughput of 20Mbps but is about 1/2 the price http://www.broadbandbuyer.co.uk/products/13120-tp-link-tl-r600vpn/

If the two buildings are fed from the same pole or cabinet it might be a fairly ( it is Openreach! ) simple job. Would save you the ongoing cost of an additional ADSL FTTC service. It would need the payback periods calculating.
