Allow WAN connection to go in

Hi…

I want to do a remote access from my office to “my internet connection at home”. I have installed Comodo but I can’t get into my pc from the office.

I can do it within the internal network but I can’t access my pc from the office.

Is there any special rule that I have to do.

I am using VNC. I have done port fowarding from my D-link ADSL modem router. Before with no firewall, my remote access working, but after I have installed Comodo, it is doesnt want to work anymore.

Here is my network diagram.

Internet <— Modem Router ← My PC

Monaro

Put this rule on top of network monitor list.
ALLOW & LOG TCP IN SOURCE [ANY] DESTINATION [ANY] WHERE SOURCE PORT IS [ANY] ANS DESTINATION PORT IS 5900
