my router access to internet and all lan access to intenet without asa

u r missing NAT configuration.
firewall NAT by default.
configure identity NAT on ASA
if router is performing NAT

Nat hasnt been a requirement on the ASA for some time. no nat-control. I think since 8.3 the command is actually deprecated.


This could be a problem for you as well with the implicit deny at the end.

access-list inside_access_in extended permit icmp any interface outside

can u correct my configration for acl u mean my acl in problem
iam waiting
best regaeds

For testing you can change to:


access-list inside_access_in extended permit ip any any



After you know everything is working, you can go ahead and tighten that acl. Do your configs in steps. Apply config, then test. Its much easier to troubleshoot this way instead of applying a full config and find out that something isn't working.

it same problem when i put access list
no ping from lan to yahoo
no ping from lan to 4.4.4.4
can u paste complete configuration to only access to internet and allow all
for testing
best regards
