Is NAT-T enabled on the client? To check from the initial client screen, highlight the VPN connection, click the `Modify' tab, then click the `Transport' tab. Ensure that the `Enable Transparent Tunneling' box is ticked and the `IPSec over UDP' is checked.
If this is done does it work?
If not this may still be a NAT issue, but at the ADSL router end. Does your ADSL router provide for PAT (NAT overload), can the users make simultaneous connections to Internet sites ?
here my ADSL connection doesnt have a Permanent static IP.It's from a DHCP pool from the ISP side.
IP address of ADSL interface may change after some days.my H.O side is one Cisco router & PIX 515E.remote side is adsl connection that's not cisco,i think its a D-Link.In this scenario how can i achieve this.is there any settings in VPN client software.
