Help - How to block port 80 (outgoing)

[Mike Galloway]

For some reason, I cannot get out of my system using wget, curl, or even telnet via
port 80. All programs responds with (no route to host). I believe there is some type of firewall or port blocking mechanism that is blocking all traffic outbound to port 80.

So I am asking how to block a port so I can check if that has been done.
I am running RH 7.2

If I use wget or curl to port 443 (secure) it works. If I ping to a host, it works, just port 80 is
affected.

Here is output from iptables -L

[root@ns1 mike]# /sbin/iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
