no access-list ping_acl permit icmp any any

no access-group ping_acl in interface inside

You do not need this acl to allow ping from the inside interface. Removing this acl will solve your dns problems etc. If you want to ping to the outside you only need to allow the reply in the outside interface acl like so...

access-list acl_out permit icmp any any echo-reply

Please rate if this helps.

Is there an acl on the inside interface?

hi,

Yes, just one to permit ping :

access-list ping_acl permit icmp any any

access-group ping_acl in interface inside

Find attached the configuration file.

Hello.

The ping_acl is your problem.

You will need to add a line allowing users port 80 connections out (there maybe other ports required also)

ok,

addind a line like with an acl? how ?

access-list out_acl permit tcp inside-network any eq 80

is it correct ?
