I want to create a VPN tunnel between sites.
To explain my current network configuration please see the attached diagram. Site A has a Juniper firewall SRX345 with a public IP address, and site B has a 4G broadband router with a private IP address. Currently, site A has a switch and it has VLAN 300 configured and many devices are connected to that VLAN 300. I want to create a VPN tunnel between the two sites and provide access to the VLAN 300 on site B. So any device can easily connect to the same VLAN 300 on site B. Both devices A and B should be able to talk to each other as they will be in the same network. Is there any guidance for this type of configuration? If someone can provide a detail guide that would be great.
