Do you use the Checkpoint VPN client to connect to the ASA? Why don't you use the Cisco VPN client or the embedded Microsoft Windows XP client?



Hi Daniel,

Its not like that ,My office is in India and I am using ASA in my network , our one of the client is in USA they sent me the checkpoint client means clients are using checkpoint firewall. and after configure the checkpoint client in my pc I am able to connect their network . but after connect VPN client succefully I am not able to connect my own local network.

Try to open the following ports and see if it helps:


The UDP encapsulation port might be configured differently on the Chkpt, you the admin should be able to tell you what it is.

What strikes me is the huge number of ports this client needs for some of its functions:


Please rate if this helped.
