I dont know why I always end up asking about strange setups and routing things 🙂
On the above picture you see my "predicament" .
All sites are connected to the internet, and uses the HostingcenterMX as a HUB for AutoVPN.
The Hostingcenter is also advertising static routes to the Servers in AutoVPN.
Now because Internet connection to Site03 is really dodgy, theres an MPLS connection between the Hosting center and Site03.
Is it possible, (when setting up the static routes on Site03 towards the rest of the net over the MPLS, and on the HostingcenterMX towards Site03 over the MPLS) to get all traffic from fx. Site 01 or 02 routed over AutoVPN to the hostingcenter, and then the hostingcenter MX will route it over the MPLS to Site03 (and vise versa from Site03 -> Over MPLS -> Hostingcenter -> Site02 or 01 over AutoVPN) - AND .... if the MPLS fails, have it (Site03) all failover to AutoVPN through the Hostingcenter - (or just MESH dont really care in a failover situation - just as long as there's some kind of connection between sites).
And now Ill start to answer my own questions 🙂
My guess is no, because i will need to make the static route to the MPLS and Site03 on the HostingcenterMX "in vpn", and then I will have overlapping IPs between the AutoVPN and MPLS.
Is it possible ? Am I missing something ?
The only backup plan I have is not using AutoVPN on Site03, and just having it fail if the MPLS goes down (of course they will still have their dodgy internet connection).
OR --- Could this NO-NAT feature I have heard about save me ? By plugging in the MPLS connection on the DC site and on Site03 into Internet 2 ?
