I am trying to access my desktop computer on my home network remotely over the Internet from my laptop using Microsoft s Remote Desktop Connection.
Since my ISP issues Dynamic IP addresses, I subscribe to No-IP.com for a free sub-domain, so that I don t have to worry about IP addresses constantly changing in the future.
I m looking for some help on how to create ZoneAlarm firewall rule(s) that will allow me to access my home desktop computer using my laptop regardless of
the IP address that gets assigned to my laptop.
As long as I know the IP address assigned to my laptop, I can create a specific firewall on my home desktop computer to allow access for my laptop computer.
I ve demonstrated that I can do this and it worked.
I was able to logon to my home desktop computer using Microsoft s Remote Desktop Connection because I allowed ZoneAlarm for the specific IP address assigned to my laptop to gain access.
Where the problem arises is when I attempt to access my home desktop computer from a different wireless Access Point (AP) using a different IP address for my laptop.
ZoneAlarm blocks my access.
I tried creating a firewall rule under the expert tab to allow access, but ZoneAlarm still blocks access.
Here is some relevant information
Let s say the host name for my laptop is called Laptop
Let s say the host name for my desktop is called Server
Let s say my domain name through No-IP.com is called laptop.no-ip.org
I use a D-Link DI-624 wireless router connected to my Internet cable modem.
I ve configured the router to allow access through for Remote Desktop Connection and that works.
I ve also assigned my home desktop computer a static IP address of 192.168.0.105.
Here is the firewall rule that I created that is not working
Source: Host name is laptop.no-ip.org . Lookup returns the correct IP address.
Destination: Specify an IP address of 192.168.0.105.
Protocol: S pecified Any (although I m not comfortable using Any ).
Time: Specified Any .
When I look in the ZoneAlarm log, it tells me access is blocked.
It appends a 5-digit number after the source IP.
Every attempt that I make this number seem to increment.
I'm assuming this is some sort of port number?
Maybe I m not setting up the rule properly or what I m trying to do is not possible.
Can someone provide me some assistance?
