My work network is 10.1.x.x. My home network is 192.168.10.x. I have a TP-Link TL-ER604W router that maintains an always on IPSec VPN connection to my work Sonicwall firewall using IKE. I can ping any IP address at work from home and any IP address at home from work. It has been working fine for a year. I recently put together a backup system consisting of a Dell Optiplex running CentOS (IP with a WD DL4100 NAS (IP that connects to the Dell with iSCSI. The Dell is running a software version of the WD Arkeia backup. I have an Arkeia appliance at work as well. Once I fill up the Dell/NAS with backups from the Arkeia appliance I intend to take those two devices home to fill the role of cloud backup away from work and replicate to them. I would like to just take the Dell/NAS home and connect them to my home network with no IP changes since it would be convenient to be able to take the Dell/NAS back and forth but this will not work. I tested it by taking a laptop home and assigning it IP I was hoping since I could ping both ways that I could ping to or from but since this is not on my home network, the packets don't know where to go. Is there any way to configure my home router to allow the Dell/NAS systems to communicate without changing them to my home IP network scheme? I know if I changed the Dell/NAS boxes to 192.168.10.x it would work fine from home. I do not know Linux very well so making these IP address changes is difficult for me especially if I end up taking it back to work now and then?
