Hi Alan,
Thank you so much.

when i set one client server to my radius server ,the vpn users work fine.
but while there are two client servers ,the second client cant connect the
radius server.
radius server : client.conf
--------------
client [vpn1-IP]{
        secret = secret1
        nastype = other
}
client  [vpn2-IP]{
        secret = secret2
        nastype = other
}
-------------
radius.log

the second client server log
-----------
Sep 17 04:18:19 vpn2 pppd[8096]: pppd 2.4.5 started by root, uid 0
Sep 17 04:18:19 vpn2 pppd[8096]: Using interface ppp0

Sep 17 04:18:53 vpn2 pppd[8096]: rc_send_server: no reply from RADIUS

Sep 17 04:18:53 vpn2 pppd[8096]: Peer vpn2test01 failed CHAP authentication
Sep 17 04:18:53 vpn2 pppd[8096]: Modem hangup
Sep 17 04:18:53 vpn2 pppd[8096]: Connection terminated.
Sep 17 04:18:53 vpn2 pppd[8096]: Exit.
------------------

If there is only vpn1 client, the client server and radius all ok ,while
two , the vpn1 still wor fine, but the vpn2 is not.
Why the radius server cant make response to the vpn2 client server?

Thanks.
