Are you sure this a router issue and not some firewall preventing access?
My Netgear RP614 v.2 router has begun "disallowing" certain sites to be accessed, with no changes or input from me. The biggest site in question is USPS.com, which is a vital part of running my business. I can access the site with the router bypassed. I have upgraded the router's software, reset all defaults, adjusted MTU, etc., with no results. I spoke with Netgear and they suggested that I will need to obtain the USPS.com port number(s) and manually input them into the router. My question is how do I obtain such port numbers, and how do I input them into the router, "forcing" it to allow that site?
Any help would be very much appreciated!
