Hi Fulvio,
I enjoy using zeroshell for wan and vpn management with untangle for the lan side, it will be very useful for me if you can integrate dnsmasq (v2.48 mini) for using its dhcp proxy functionality (I often have routers or boxes acting as dhcp servers without control of them , tftp options, pxe boot,..) and also a program like fetchmail so i can poll POP or IMAP external servers and delivering mails via SMTP to internal mail server passing this traffic to the antispam blocker of untangle.
Thanks for this great job
