IPSec Peer not available when connecting via Client VPN

[StarZen]

We have an IPSec peer connected to our MX

all is find when connected to the MX but when we connect to the MX via client VPN (laptops out of office etc) the IPSec peer network is not available

guessing this is some routing issue but not sure where to even look

any help greatly appreciated

I do not believe you can access a third party VPN when connected via the Client VPN. 

The caveat here under IPSec VPNs, applies to clients as well: https://documentation.meraki.com/SASE_and_SD-WAN/MX/Design_and_Configure/Configuration_Guides/Networ...

You either need to remote into a device that client VPN can access or you could put the third party VPN on another device and use static routing from the MX to route to it, or you may be able to use BGP as noted at the link. Someone else may be able to confirm if that will work or not. I don't use it so am not certain.

It should work if you use BGP.

At a minimum, you would need to ensure the client VPN subnet was included on both ends of the VPN to ensure it works.

But I like @alemabrahao BGP IPSec answer best.
