I am setting up my Meraki MX250 and MX68 for site to site VPN. I am having an issue that I can't resolve. My clients on the 68 are not getting IP addresses from my Servers behind the 250.
On the MX250 I have a VLAN with the scope of192.168.4.0/24and this is where my servers sit. On the MX68 I have a VLAN of192.168.5.0/24and that is the client scope at the remote site.
I have the MX68 relaying the 5.0/24 VLAN to the DHCP servers on the other subnet.
My VLAN 4.0/24 is on port 3 of the MX250 and it is a trunk port. My VLAN 5.0/24 is on port 3 of the MX68 and it is an access port with the access policy as "Open".
Both MXs are in Routed mode with MAC Address Client Tracking.
My DHCP servers have both a192.168.4.0/24and 192.168.5.0/24 scope set up. The 003 Router option on my 5.0 scope is set to 192.168.5.1 and that is the same as my VLAN MX IP gateway.
One thing I have noticed is that if I add192.168.4.1(gateway for MX250) to the192.168.5.0/24scope Router option, the MX68 will then see the client but the client will still not be reachable by ping or have internet access.
Sorry, this was a lot of words but I am not sure what info might be needed.
Just to close this out. I did get everything working just not the way I would have liked. I let the MX68 play DHCP for that remote office and set it up to give out the scope I wanted. Now everything is working fine. I never did VLAN to pass DHCP relay.
