Some Hosts unable to communicate in transparent firewall

[sallu]

Hello,

I configured a transparent firewall using the guide:

http://people.pharmacy.purdue.edu/~tarrh/Transparent%20Firewall-Filtering%20Bridge%20-%20pfSense%202.0.2%20By%20William%20Tarrh.pdf

The firewall runs fine for few minutes but soon some of the hosts are unable to access the Internet. Can anyone explain?

I am assuming the firewall is auto blocking for bad packets etc.

Thanks.

If you look in the firewall log, you can see why the connections are being blocked. If they're not in the log, then it's probably some other problem.
