hey i have noticed that i have port 5000, 53, 23, and 80. 80 and 5000 are tcpwrapped. I blocked dropped incoming and outgoing packets on the upnp port 5000 in my iptables and disabled it on my routers server. As well and telnet. For some reason though, these ports remain open on my routers server even though i have blocked them. I ran over my router with nmap and got this
Code:
PORT STATE SERVICE VERSION
23/tcp open telnet?
53/tcp open domain?
80/tcp open tcpwrapped
5000/tcp open tcpwrapped

How can i fix this? Should this be a concern?
