Hey,
Apply the following config in the ASA. You can copy and paste the whole config. After that disconnect the vpn client and reconnect it and hope that will work..
tunnel-group CPL general-attributes
no address-pool Remote_Client_Pool
exit
no ip local pool Remote_Client_Pool 10.3.254.10-10.3.254.60 mask 255.255.255.0
no access-list inside_nat0_outbound extended permit ip 10.3.254.0 255.255.255.0 10.3.254.0 255.255.255.192
no access-list inside_nat0_outbound extended permit ip 10.3.4.0 255.255.255.0 10.3.254.0 255.255.255.192

Cisco always suggest to have a different Ip pool subnet than what you are using in the internal interface for avoid any possible routing conflicts.
