Virtual IP Duplicated on Interface Change

stompro · May 3, 2013, 9:15 PM

Hello, I just noticed this on a test machine and I'm wondering if this would be considered a bug.

Running 2.1-Beta1(i386) Thur May 2 build on a netgate Hamakua-1U.

I have 12 Virtual IP's setup on my wan interface. I changed the physical interface that the wan interface is associated with. When I looked at the ifconfig, I see that the virtual IP's are now setup for both the old and new interfaces. It looks like the code that deals with interface reassignment may need to remove the virual ip's when there is a change.

Should I file this as a bug? Or is this something else I'm running into. I'll make sure I can reproduce the problem next week.

If that's reproducible, yeah please file a bug report with steps to replicate.

The situation does clear up after a reboot, but comes back when I change the wan interface again. I will file a bug report.
