Hi,

You need to make sure you have the following configured

  • same-security-traffic permit intra-interface
    • This will allow the VPN Client traffic to enter the ASA and leave it through the same interface
  • If you are using Split Tunnel ACL with the VPN Client, make sure that the ACL has the Remote Site network included
    • If you are using Full Tunnel this wont be an issue
  • Make sure that the L2L VPN ACL that defines the "interesting traffic" includes the VPN Client Pool on both sides of the L2L VPN
  • Configure a NAT0 on the VPN Client ASA "outside" interface that does NAT0 for VPN Client Pool to Remote Site Network

If you have some actual configuration to share I can try to help with those. Otherwise I can only give some general things like the ones above to check.
