I purchased a Cisco RV320 last week and am trying to set up port forwarding on it. I already have 5 rules enabled, and they all work. However, whenever I try to add a new rule, I get the error "Service Name should be different!", which is undocumented anywhere. If I try to delete an existing port forwarding rule, then I get the error "Critical failure. Please contact support." The router is running the latest firmware 1.1.1.06.
Does anyone have any suggestions as to how to get port forwarding working again? I would prefer to avoid a reset to defaults at all costs because the router is located 200 miles away and the people who I would have to talk to on the site to reconfigure it have nearly zero experience with networking.
Thanks for the help in advance.
