Self-update :D

I have updated the settings and now am only using IPaddr instead of the *2 version and now at least I can see the virtual ip.

I also commented out the device (dunno if I should put in eth0 or eth0:0)
and changed the virtual ip to 150.158.1.5

now I am getting this error

Anyone?

BTW: I'm not a network expert, so please highlight any issues.

thanks
