Hi,
I am also facing the same problem with the firewall.
Recently I have installed "avast! Mobile Security" and everything works fine except 'Firewall'.
If I enable Firewall, none of the applications listed in the Firewall section is able to access Internet. If I disable the Firewall, all the applications are able to access Internet.
I have given full permission to the "avast! Mobile Security" in the Firewall, but when I try to do the 'Check for updates now' option in the 'Settings' section, it displays this message: "Connection to the update server failed. Check your Internet connectivity and try again."
My Android phone configuration is as follows:
Device: LG Optimus One P500
Android version: 2.3.3 (Rooted)
Kernel version: 2.6.35.10
Anyway, lot of thanks to the "avast!" team for developing such a feature rich application.
Now I am a fan of "avast!" products. Inspired from "avast! mobile Security", I've installed "avast! Antivirus" on my desktop and laptop, and now I am recommending "avast!" products to my friends..!!
Update:
There is no problem in the avast! Firewall functionality..!!
Now all applications are allowed/restricted to access Internet based on the Firewall rules set. The problem was in understanding the working of (Wi-Fi/3G/Roaming) buttons given for each application in the 'Firewall' section.
What I understand is given below, may help anyone facing problems with the 'Firewall':
If you select any button(eg.,Wi-Fi button, its color changes to black when selected) given against a specific application, you are enabling 'Firewall' for that type(eg., Wi-Fi) thus blocking that application from using that(eg., Wi-Fi) type of service.
Thanks,
