I have some web cameras on my network using a Westell 327W router. The public ip keeps changing so I cannot see the cameras from a remote location. I have set up a dyndns account which I am told will allow me to send the current ip address from the router. I do not know how to send that address using the modem. There is normally no computer on the network - just the three cameras and the router. Am not very knowledgeable about this so please be basic with any help. Thanks.
