Azure routing | from p2s client VPN to s2s network on-prem

Hi,

We are trying to connect a machine behind a p2s connection to a network which lies behind a s2s connection through Azure.

on-prem < site-to-site > Azure vNet < point-to-site > client machine

I have read about that we should use BGP between on-prem and Azure vNet in order to advertise the routes but in our case we can not do that because we have Meraki MX which does not support BGP with non-meraki peers.

What we have done until now is that we have created custom rules on a routing table on Azure and attached this with the vNet which both of sites are connected to. On the client machine behind the p2s there is a route to the vNet via the p2s connection (route print shows that) but we also have a route to the on-prem network via this connection. But the problem is that we still can not connect to the on-prem network via p2s client machine.

My question is this, is this even possible to connect via custom routes or is it only via BGP that this is possible?

@FisnikMagashi-8490 Thank you for reaching out to us on Microsoft Q&A. We apologize for the delay in response.

I understand that you are trying to connect from P2S client to on-prem via S2S VPN. However, this requires the S2S VPN to be using BGP as given here in this document. At the moment there is no work around for this and therefore will not work without BGP.

I hope this answered your questions. Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
