Description Need Real Name 2003-04-09 13:40:52 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225

Description of problem:
My security setting is set to high, with ppp0 as a trusted device.

I have "customize" selected. I do not allow *any* incoming services, but still
have entries from outside in my apache log file.

How reproducible:
Always

Steps to Reproduce:
1. Security level: high
2. Select "customize"
3. Select "ppp0" as a trusted device.
4. Ensure nothing under "allow incoming" is selected.

Additional info:

Rebooting doesn't change anything.
Comment 1 Michael Young 2003-04-10 03:13:53 EDT
I thought that a "trusted device" meant that you trusted (ie. allowed) all
traffic from that device, and the firewall setting only applied to non-trusted
devices.
Comment 2 Mark J. Cox (Product Security) 2003-04-10 04:20:51 EDT
This is expected behaviour, trusted devices are exempt from the firewall rules.  See
www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/
custom-guide/ch-basic-firewall.html 
Comment 3 Need Real Name 2003-04-10 13:19:16 EDT
I think the manual could be clearer:

"..Selecting any of the Trusted Devices allows access *to* your system for
all traffic *from* that device.."

and the gui should give a warning.

This is a dupe of 88136
