I have peplink balance 305. 5.4.8 build 2532
I have added many port forwards without problems.
Today when I try to add a new one, i get an error message:
“please select at least Connection / IP address for the service rule.”
I have the connection and WAN IP checked/selected.
I have tried different variations such as single port, port range, port mapping. all give same error.
I deleted server and added back. no joy.
all other port forwards (22 in total) have worked fine.
