Virtual private networks / NAT ipsec VPN tunnel
July 30, 2024, 08:46:03 AM
Hi guys,
New at opnsense here. I have a new client that is using opnsense. On my side I have Sophos XG appliance.
The issue is that the customers from before are using the same local subnet as is this new customer.
We need to create a NAT VPN tunnel.

New customer ( Customer A) is using 192.168.0.0/21 subnet.
That interferes with already existing 192.168.0.0/24 on another customer.

We would like to use 172.24.0.0/24 subnet to connect to new customer.
Bare in mind, there are alreday cca 80 hosts in this 192.168.0.0/21 subnet.

We need to be able to acces those clients with their existing IP addresses (for example 192.168.6.12) throught the vpn tunnel .

Can anyone help?
