Samsung Galaxy Tab S firewall configuration

I have a Samsung Galaxy Tab S and I wish to disable or configure the firewall so that applications on the device can listen on specific IP addresses for UDP, TCP and multicast traffic.

How can i do this please ?
Please note that this is not a phone it is a tablet, I have posted to thr Smartphones section as there is no section for tablet devices.

There is no firewall by default on the Galaxy Tab..unless you are referring to an apps such as those in below, the config may be specific to them and good to get their doc to check for such use case mentioned

There are none of the programs such as those listed at the link that you suggest.
I need an application which listens on a specific port and can demonstrate that there is nothing preventing reception of the specific port. Any port would do, just to confirm that there is no firewall blocking reception of IP traffic.

Network Log (more preferable but for rooted and may be restricted)
The log tab shows the network packets being transmitted and their details such as:
* source and destination addresses/ports
* network protocol and interface
* bytes transmitted
* timestamp

I will try networklog and respond tomorrow, thanks.

I installed networklog but if I try to turn logging on I get an error message "Network Log requires root/superuser access"
Can I assign these rights to the app ?
btanExec ConsultantCommented:
since it has to be at the system level to look into the packet, and it required the device to be rooted (as I prev mentioned) hence its request.
Network Log monitors iptables-logging to display a real-time list of which apps are making network connections, and provides statistics about those app connections.
 
Requires root: Yes. iptables must run as root

Can I make the device rooted ?
btanExec ConsultantCommented:
wearing security hat, advice is not to root as it will then open up to even malware if the device is not properly managed. wearing the user hat, advice is you call the shots. The device is for testing and managed enterprise device, you can decide.

In your use case, most of the time you cannot avoid rooting this, otherwise you cannot reached that network vsisibility depth w/o the administrative rights ...maybe there is other means like debugging (see this via DDMS which interact with debugger - http://developer.android.com/tools/debugging/ddms.html#network) but I see no harm (but pse do backup before rooting)  doing it on the apps for a test out (note the ROM compatible warning on the apps calling)

Having said that, i saw tPacketCapture does not need to be rooted, if you want to check out the feature depth
