I am looking for standalone router device preferably without WIFI to act as a L2TP/IPSec VPN client to ISA 2006 server. Main purpose for this is to extend our corporate VOIP to telecommuting users via MS ISA. I know that there are better ways of accomplishing this by switching to different VPN solution but unfortunately I do not have that privilege. I would appreciate if someone would let me know if this is possible with zeroshell or any other embedded solution.
