Until recently (I can't put a definite date on it as long gaps between when I have used it previously) I have had a port forward set up (so I can access my NAS) and it has worked perfectly. However when I tried the other day it didn't work. A bit of digging and the IP address had changed. However when I now try to access using that IP I get time out errors. I've checked the rule and all seems to be in order as follows
I did run Windows network diagnostics, and used canyouseeme as follows
Nothing has changed to my knowledge in anything else on the network or NAS, so I am really not sure why this is not working? Any thoughts gratefully received.
