NAT destination network through an specific VPN

Hi everyone. I'm having a problem with a specific configuration.

First of all, my local net is 10.0.0.0/8

I've connected successfully my Sophos XG 230 to a IPSEC VPN with the next network configuration (yes, an /32 network).

The VPN is NATted to "RED 10.0.0.X" which is the network 10.0.0.0/8. Therefore all my network can reach the IP 10.192.214.33 easily

This is so because de remote net only have to receive all the traffic through the IP 192.168.226.17.

Now, I need to reach to the IP 172.29.4.212 through this VPN but I don't find the way.

I've tried several ways but I can't do this:

• creating a firewall rule (i cant route the traffic because there isn't a gateway to this VPN)
• can't create a group of networks to try to nat them in the VPN configuration
• etc.

Could you help me?

Thank you very much.
