Hi Joseph

The consequence of the bad dns was after I forced the dhcp to send a client request to the gateway for the server to send me dhcp lease details again....only then I got ip reachability to the gateway address but after with a resolution problem, need to understand what causes the lockup though...

On auto nat have some untranslated hits from other inside traffic that I need to figure out..

ciscoasa# show nat
Manual NAT Policies (Section 1)
1 (inside) to (outside) source static any any destination static NETWORK_OBJ_192.168.2.0_28 NETWORK_OBJ_192.168.2.0_28
    translate_hits = 4, untranslate_hits = 0

Auto NAT Policies (Section 2)
1 (inside) to (outside) source dynamic obj_any interface
    translate_hits = 127900, untranslate_hits = 24979

Manual NAT Policies (Section 3)
1 (outside) to (outside) source dynamic SSLVPN_ON_A_STICK_1.1.1.0_29 interface
    translate_hits = 0, untranslate_hits = 0
