Must the vpn3002 hardware client associate with a concentrator? Could it associate with another type of ipsec server? Yes, no?
We have an office and some people who telecommute. We would like to put ip phones at their office. The problem is at our office the only high access we can get is cable, and we only have two static ips for that. So everything is natted with overloading. We don't se any way to get the phones to work except to install a vpn... or host all of our servers elsewhere...
Beware of running IP phones over a VPN, especially if you have no control of the quality of service of the data link. Voice traffic on IP will onlt work well in environments with controllerd delay, jitter, and packet loss. Unless your cable provider offers Service Level Agreements comatible with voice traffic, running voice over VPN can be a risk.
That being said, there are companies with home workers using IP phones with G.729 compression over public, non QoS ISP links with acceptable results. I personally have a 7960 at home running over a 768k DSL link with tolerable quality.
Can these terminate on things other than Cisco concentrators? The documentation says:
The 3002 hardware client supports the Cisco VPN Client Release 3.0 client protocol allowing it to connect to any Cisco central site VPN concentrator in addition to the VPN 3000 such as the PIX (currently in beta) VPN 5000, and IOS. PIX and VPN 3000 connectivity are available today, while near term releases in VPN 5000 and IOS devices will provide that connectivity shortly. In addition, the VPN 3002 Hardware Client works in conjunction with any operating system including Solaris, Mac and Linux.
Does the sentence mean that clients on other os's can use the 3002 or that the 3002 can terminate on an ipsec server that runs on other os's?
The 3002's are designed to connect to other Cisco devices only. I'm not certain why that last sentence about the OS's is in there unless they are referring to OS's you can use to configure the 3002. Otherwise, I imagine any network device sitting behind a 3002 is compatible.
