Dear support community:

We're trying to connect VPN between Linksys Cisco RV082 (Gateway) and Cisco RV042 (Router) on a lab setting. We're able the configuration gateway-to-gateway, but after to click save values, the ip address they change automatically.

IP 192.168.1.8 it’s change for this IP 192.168.1.0

Can you please help me find what's wrong?

Thanks in advance.

Hello ojuarez011,

       I believe the reason the IP address is changing is because you have a subnet mask of /24.  This would include the whole class C subnet of 192.168.1.0 so it defaults back to the network address.  If you are only wanting to allow 192.168.1.8 through the VPN from that site, try a subnet mask of /32 or 255.255.255.255 and see if the address changes then.  Hope this helps.
