I have a vpn 3030 concentrator .My client maybe connect the concentrator through adsl. I want to know whether the client should has a public ip address or can use private ip address through pat or nat to connect the internet?
If they use a public address, then it is a normal connection. If it is using a private addr, and then
there is a device doing nat or pat, then you could use IPSec thru UDP or IPSec thru TCP, designed to deal with this kind of scenarios. IPSec thru UDP is a group attribute on the 3000, while the TCP is a global attribute. Both should be enabled on the client properties, depending which method would be used. See materials on:
