You can configure Source Network Address Translation (SNAT) over an IPSec tunnel to ensure that all communication with the IPSec device originates from a specific IP address. In your case, you want all communication to the IPSec device to go through the local subnet IP 192.168.77.1/32.

Here's a general outline of how you can achieve this:

Configure SNAT on your local network device or firewall to translate the source IP address of the outgoing packets to 192.168.77.1.

Ensure that the IPSec tunnel is properly configured to allow traffic from the local subnet 192.168.77.1/32 to the remote subnet 172.17.17.9/32.

Verify that the routing is correctly set up to direct traffic intended for the remote subnet through the IPSec tunnel.

It's important to note that the specific steps to configure SNAT over an IPSec tunnel can vary depending on the devices and software you are using.
