Possible issue importing old rules to new system.

[awshirley]

I'm getting this error message when I tried to import my old rules csv:

e1e633f9-c53c-4391-b640-adc9c7b82d65,1,keep,,451,pass,1,0,lo0,in,inet,any,,,,,0,0,0,0,0,,,,,,,,,,,,,,,,,,,,,,,,0,any,,0,any,
[interface] Option [lo0] not in list.

It looks like the other rules imported expect this one.  I'm not exactly sure what the problem is.  I've reviewed all the old rules and I don't have an lo0 interface.

Thanks!
