Any recommandations? Regards

Hi, Thank you for your post here. From the description, you have two sites that will be joined together through public internet. Why not assigning other private IPv4 subnets such as 192.168.0.0/24 or 172.16.0.0/16? Am I missing something?

192.168.x.x or 172.16.x.x is ok The reason i ask is i may have to trust both network(2 -dc's),create VPN May me if i would assignto second DC 10.0.100.1 it will be easy to configure? Thnaks for replay

I suggest you to use 192.168.1.0/24 and 192.168.2.0/24 (or any other private network that have enough host addresses) - both VPN sites must be in different subnets otherwise you'll get troubles with routing. You may use single subnet only if VPN is made through a hardware tunnel (most ISP offer this option but it's quite expensive). You cannot assign 2nd DC an IP 10.0.100.1 while using /8 network mask - it will be the same subnet.Valeriy Shevtsov, MCT
