[Soekris] What to do with my old 4501

[Ronald L. Rosson Jr.]

I currently have a NET4501 sitting on the shelf doing nothing since  
it was replaced by my NET4801 as a firewall running pfSense.

I am looking for a low cost solution to have this system do something  
that can benefit my network that the NET4801 is not doing at the moment.

any idea?

TIA
