Allow access to device and no internet

Matt Roberts — Wed, 13 Mar 2019 01:10:03 GMT

Tried to configure access to device through firewall by giving it a static NAT and ACL rule but no luck. The device also doesn't have internet access not sure what I have configured wrong. Please help

Hi Matt,

Hi Matt,

first steps should always be packet tracer, sh xlat, show conn, show access-list etc...

can you ping 8.8.8.8 from the ASA-console?

do you have match counters on the ACL? (show access-list)

do you have active connections in the conn table when you try to reach a destination on the internet? (show conn)

does the xlate look somehow reasonable? (show xlate)

try the packet tracer, it's quite intuitive on the GUI. what's the output? (tools -> packet tracer)

as long as the ASA is non-productive debugging with packet capture: http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/118097-configure-asa-00.html
