Extend Aerohive WLAN over WAN

we have a Branch-Router infrastructur at one of our schools. Actually there is one SSID with a guest use network for the students. The school has a second campus with no direct connection to the main campus but with its own WAN connection. What we want to do is to extend the students-network to that campus over another branch router. So I have configured a second branch router, added it to the school policy and connected it to the internet connection of the 2nd campus. Branch router comes up. Then I configured an access point (ap230) and plugged it to the new branch router. Access point also comes up and offers me the students SSID. With an notebook I could connect to the students-SSID but I do not get an IP-adress via DHCP on the students-VLAN.
Is there anything else I need to do?

Thanks a lot,

hi jennelu,

you should have configured a DHCP for the Network you setup while configuring the VLAN. Be aware your DHCP is still local, so your router must offer the right pool for the right VLAN

Hi thanks for your reply. Unfortunately I do not understand what you mean. Please take a look at my graphic:

- The network object "school" (192.168.252/23) is actually defined as guest use network
- Side B is working actually (I can connect via PPSK, get an ip address from the pool
- Whats working on Side C: I can see the SSID "school" from the access points, can connect via existing PPSK
- Whats not working on Side C: Because there is no direct connection between site B and C, I do not get an ip address for my client via dhcp

Now what I want to know is, if there is any possibility to add a new VLAN subnet for the existing user-profile "school" on side C with an dhcp-server on branch-router 2 so that the clients on site C get an ip address via dhcp?
My second question is (if the first one is possible): Can I set up routing between the school-subnets so that the clients on site C can connect the server on site B?

Big thanks for your help!

Easiest according to me is configuring DHCP on branch router in site C like you said. Other possibility is using same server in site B, but then you should relay the dhcp requests to router in site B (using an ip helpder address). Then clients in site C will also get an ip address from site B. 

Once the clients get an ip address in site c they should connect to site A, so if routing between site A & B is fine, the clients will be able to connect to the server in site B.
