when I am trying to access client VPN(PPTP) from my DHCP IP , I am getting Error-619, but If I am trying to access same VPN thru one to One NAT IP, then I am able to access. please tell me why I am not accessing thru DHCP IP.in my network I am using ASA5510.
Please follow the examples provided on this link pertaining to PPTP and ASA version 7.x to 8.x..
if you are using PAT for outbound PPTP connections you must have pptp inspection in your global policy.. because you are using one to one NAT I suspect you do not have pptp inspection configured, your dhcp addresses are most likely PATed for outbound connections.
