what's more ,i found that whichever vpn user to radius server, all shows
the same nasipadress, so i set different nas-ip-address in the radreply
table for users in different client server, but sitll show the same
nasipadrees.

In my radcheck, i created vpn1user and vpn2user for different client
servers, but it seems that it cant distinguish users for different clients.
For example, the vpn2user with vpn1 server IP can also connect to the
radius server.

How can i sove this?
Thanks.
