Cross backup
-
Dear all ! ..
As a newby I hope someone can give me a "push"in the right direction …because I struggling already for weeks !
I want to make a crossbackup through one Synology > pfsense over the internet to one another pfsense >Synology Nas ...as my friend does vice -versa! .We also want a regular check with separate OpenVPN connection if the backup succeeded or not ! ..How does one work ?...how doe I roughly make this work ?...Do I need twee openVPN servers..two gateways .....separate interfaces..?...
Can the synology still reaches te Internet while making his backup through a VPN connection...?Ik really hope that someone can help me out !
Appologize my english ! -
You can make a site-to-site shared key OpenVPN TUN link between the 2 pfSense. Make sure your LANs are different IP subnets - e.g. 10.20.1.0/24 and 10.20.2.0/24. Use another subnet for the OpenVPN link "tunnel network", e.g. 10.20.3.0/24.
Then add pass rules on the OpenVPN at each end to allow whatever traffic you want - e.g. if you are friendly with each other you might allow all, or you might just allow traffic between the IP addresses of your NAS boxes.
Of course, if you backup many GB of files then you will need a fast internet connection and plenty of quota from your ISP. -
Also, whichever end is the OpenVPN server will need to have a known public IP address so the client can connect. If one of you already has a static IP, then use that for the server end. Otherwise you will have to sign up to a dynamic DNS service. pfSense can keep the dynamic DNS name up-to-date with the current IP address of your OpenVPN server end - Services->Dynamic DNS.
