SSL VPN Appliance

Hi all,

I''m looking for a inexpensive (under $500.00 or open source) but reliable clientless SSL VPN appliance solutions. I know there are firewalls with the function built-in but would prefer a dedicated appliance.

I looked into ADITO, and looks good but after researching it appears to have some security holes due to lack of update.

Any suggestions are greatly appreciated.

Thanks

Rudy
