Hello Nicholas,
Thanks for contacting Cisco support community centre.
I hope you are doing well. I am really sorry for inconvenience caused and delay in response. Please change he Dynamic Routing working mode to “Gateway” under Setup à Advance routing. Make sure RV325 WAN IP is not in its own LAN range (192.168.1.X, 2.X, 3.X), if WAN and LAN IP are on same range, please change LAN range. If you need to configure static route, Destination IP: Subnetwork address of the remote LAN segment. For a Class C IP domain, the network address is the first three fields of the Destination LAN IP; the last field should be 0. Subnet Mask (IPv4 only): Subnetwork mask used on the destination LAN IP domain. For Class C IP domains, the subnet mask is typically 255.255.255.0. Default Gateway: IP address of the router of last resort.
Please reach out our SBSC team and raise service request to proceed further.
