We are planning new Help Desk connectivity from one of our Poland location .We want people sitting at Poland able to access some of our site locations (only European sites not american.We have got subnet that are being used for European site).
We are having MPLS link connected to Poland end.The users are accessing all the locations via MPLS end.
We are thinking of solution: GRE over IPSec tunnel (site to site VPN) for New requirement where that specific subnet can access only European sites.We will be configuring the tunnel from Poland to one of Hub location .i.e UK .
Can you please suggest best solution to implement it .
