I need to switch out our router which is no longer accessible because a factory reset is needed. With that in mind I need to add all of the necessary ports to the router firewall section and am wondering if there's a fail safe list available that includes all of the ports needed.
There are users who are working remotely and when the new router was temporarily put in place they had no access. Could somebody please let me know if there's a good list of ports that need to be added?
Thanks in advance!
