Maybe try using the global commands
no vpn-addr-assign local
no vpn-addr-assign aaa
vpn-addr-assign dhcp
And under tunnel-group COMPANY-TUNNEL-GROUP general-attributes
Add: default-group-policy COMPANY-REMOTE-ACCESS

Subject: [c-nsp] IPSec Remote Access VPN getting Addresses from the DHCP

Can u guys help me understand why the dhcp is not providing addressing
information to the VPN Clients...If I use a local pool, I can connect and
get addressing info
