We have an ASA5510 set for VPN connections. We have 3 clients that will simultaneously connect to our VPN using one Public IP since they are located in one office. I have observed that only one connection are able to successfully connect. Is there a way to allow multiple connection from a single public IP?

Hope someone will reply. Thanks.

You will want to make sure that the ASA is configured to support NAT-T. To enable NAT-T, you will issue the following command: crypto isakmp nat-traversal 10. Please test with this command in place and report back.
