Re: [PATCH 1/5] Enable correct display of ipv6 entries in Firewall log pages of web UI

Hi,

did you work out what the issue was with these emails?

Best, -Michael

3 main changes:

• Fill $iface and $out from PHYSIN and PHYSOUT when looking at

bridged packets, othewerwise fill from IN and OUT

• Recognize ipv4 and ipv6 address style for $srcaddr and $dstaddr
• Match color coding of tables to pie charts

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.
