Multiple sites, VLANs and DHCP scopes.

I've been tasked with reconstructing the network at our sites around the world. We're using UniFi with a cloud-key.

These are smaller sites with 5-12 employees at each location.

For this I was thinking about streamlining everything, same VLANs and IP scopes, which correspond to the site (10.site number.10/100/110/120/130.xxx/24) at each site.

VLANS:

• Servers:......10
• Wired:........100
• Wifi:...........110
• wifi byod:....120
• Wifi guest:...130

.

However, everything is going to be connected to our hosting center by MPLS(for sites in Denmark) and IPsec for our international sites. AFAIK the VLAN tags should be stripped when it hits the first router. But can configuring the same VLANs cause other issues I haven't considered when the traffic is sent through the VPN and ends up at the same location?

Does it make sense or am I all wrong with it?

Thank you in advance.
