Hi,
this patch is much bigger than the last one which makes it a bit difficult to review.

Updated: Enable correct display of ipv6 entries in Firewall log pages of web UI.
Generally IPFire 2 does not support IPv6, but it is enabled at some places so that it can be used. However, there will be no full IPv6 support in IPFire 2 since there is a horrible CGI web user interface which is hardly extensible.
Patches like these are okay though.
3 main changes: - Fill $iface and $out from PHYSIN and PHYSOUT when looking at bridged packets, otherwise fill from IN and OUT
This will hopefully work for IPv4 as well :)
- Recognize ipv4 and ipv6 address style for $srcaddr and $dstaddr - Match color coding of tables to pie charts (see seperate patch sent earlier)
It looks like this is included in this one as well. It would be better to have extra patches for both changes and reference the dependency in the commit message.
I am using the bridged ipv6 setup as proposed in the wiki. I do not think this breaks anything when not using ipv6. So it would be nice to include this even if ipv6 is not officially supported yet. It is quite useful when using the ipv6 setup.
@Matthias: Could you maybe review and test this patch in a non-IPv6 setup?
This is an updated version to my previous email (as a full diff to master).
What has been updated?
