Fw: Extra "Grey" interfaces on IpFire

Dear Sir or Madam,

as a Long time ipcop user i had installed this add on for a Long time and it worked great for me:

After the Switch to Ipfire as the follow-up Project to ipcop i do miss it dearly.

Is it possible to implement this functionality into IpFire? I am unfortunatley not a developer so i cant adjust the package or redesign it.

Is there a ticket somewhere to suggest Features for developement?

Thanks a lot in advance.

Yours sincerely

Klaus
