I have configured a PIX (6.11) doing VPN with client 1.1 authenticated by Cisco Secure ACS 2.6.
"isakmp client configuration address-pool local testpool outside" working fine.
However, I need to assign IP addrees through TACACS+ by user group, I removed the above line of config.
Show cry ISAKMP sa indicate OAK_ADDRESS_CONFIG and cannot get through.
