I am using a RV042G router with our system. I have a Comcast static IP address for the 3CX server. I can't seem to do the port forwarding correctly. While in the router GUI I got to Setup-->Fowarding. I put in 192.168.1.106::5060 in the IP Address field. When I click Add to List I get the error "This IP value should be in LAN or Multiple Subnet IP Range". My 3CX IP address is the 192.168.1.106 and I got the ::5060 part from the 3CX port forwarding troubleshooting guide. What am I doing wrong? TIA.
