Hey

Also modify your NAT statement

access-list NONAT permit ip 10.0.0.0 255.255.255.0 10.20.12.0 255.255.255.0

nat (inside) 0 access-list NONAT

Hope this gona solve your problem

Thanks

Hey ,

Apply the access-group policy for the access from the outside interface.

access-list 110 extended permit ip object-group VPNpool any

access-group 110 in interface outside

Thanks


Thanks a lot for  the reply Vishwa, i tried that but it still did not work. Anything else i can try?

Hey ,

Try this

no access-list 110 extended permit ip object-group VPNpool any

no access-group 110 in interface outside

access-list 110 extended permit ip oany any

access-group 110 in interface outside

Thanks

I tried that too and it still doesnt work....

Hey

Also modify your NAT statement

access-list NONAT permit ip 10.0.0.0 255.255.255.0 10.20.12.0 255.255.255.0

nat (inside) 0 access-list NONAT

Hope this gona solve your problem

Thanks

Hey

In ASA there is default policy that , you can't ping the gateway (ASA interface ip) from the different interface subnet.

In sumup you can ping the ASA interface IP from  respective  pool only.

Thanks

oh ok....thanks a lot bro..have a great day....
