Thank you for response @the_rock and @PhoneBoy
To ensure that I understand correctly, there are two types of VPN: Site-to-Site (S2S) and remote access(RA).
The difference between them is that S2S connects two networks, (An encrypted tunnel between two or more Security Gateways. Synonym: Site-to-Site VPN. Contractions: S2S VPN, S-to-S VPN.(here)).
On the other hand, remote access (RA) is used to access the device itself and connect to the internal network.
In my case, i require the second type, which is remote access (RA). In the pictures you provided, the encryption domain is set up for S2S, but since i have the S2S blade turned off, i need to configure it for RA instead?(do i understand correctly?)
In the attached picture, showing how you set up the encryption domain for RA. Could you confirm if it is correct or if there is anything what i missing?
i included the private network (that i want to access only when connected to the VPN), and i have excluded the WLAN wifi local network (the network from which i connect to the VPN).
However, even in this state, it is still not working.
