Dear  all 
 
 
 
my vpn concentrator is not able to give ip to remote access vpn client. 
concentrator is acting
as dhcp rely agent. Concentrator priviate interface is connected with a pix 
firewall dmz who is
also acting as dhcp rely for some other networks in its dmz.
 
concentrator is able to ping dhcp and all the connectivity is okay.
 
i m getting following errors while client tries to connect with concentrator.\
