Same subnets in a vpn ipsec

papali
Hi, there is a way I can connect through a vpn ipsec 2 subnets from 2 offices with the same ip address network (192.168.100.0/24) without resorting to nat or double nat??

In the attached image the idea would be that the server TELECAMERA (192.168.100.10) connects to the IP camera 192.168.100.11.

Thanks.

    If one of these two sites is under your control, the right solution is Barry's #1: change the subnet to a /24 in 172.16.0.0/12.  If not, then your only other solution is the "classic" solution suggested by yasu that has been extended in the link suggested by apijnappels.

    If you control both sites, then you'll have some command line work to do to bridge physical and VPN interfaces in both boxes, and some of what you will need to do in the UTM probably won't survive a reboot.  When's the last time you tried to put on dress socks while standing up?  If, like me, you were stubborn enough to do it once, why didn't I ever try to do it again? LOL

    Cheers - Bob
