I have a Cisco RV325 router. I'm not able to telnet to port 80 for the server on the DMZ port.
Why can't I telnet to port 80 ?
Here is what I've done:
- Connect IIS server to DMZ port
- This server has an internal static IP of 192.168.3.70
- Turned off Windows Firewall
- Connect other LAN computers to LAN ports
- These computers are on the 192.168.3.X subnet
Added access rules to allow HTTP and HTTPS, and deny all other traffic on the DMZ port.
Keep in mind that access rules are ordered. That is, when the device compares a packet against the rules, it searches from top to bottom and applies the policy for the first rule that matches it, and ignores all subsequent rules
NOTE: The access rules without a priority are the ones created by the router, by default.
I then attempted to telnet from an external computer (a computer outside the network) to port 80 of the external IP assigned to the DMZ, and it fails. For good measure, I also attempted to telnet to port 21, and it also fails.
But the router log shows :
I don't understand why I'm seeing ALLOW for the telnet attempt on port 21. And I don't understand why my telnet to port 80 isn't working.
In the end, I just want to be able to telnet to port 80.
