TELNET PORT REPORTED AS CLOSED INSTEAD OF STEALTH ON A PORT SCAN LIKE GRC
Hi, I setup the router and all seems fine as regards firewall access control and load balancing with two connections, but when I do a port scan on GRC Shields Up all blocked ports come up as stealth as it should, but Telnet port is always reported as closed even on other port scanners although its one of the blocked ports and not sure what is the casue.
Previously we had a TL-ER6020 and had no issues as regards Telnet port, not sure it I missed something as regards Remote Management or some other settings altough I checked all possible settings.
Any info appreciated what might be the casue.
Thanks
