ASA can't get to the internet HTTP but can ICMP.

kevin.cooke — Tue, 12 Mar 2019 01:22:27 GMT

I have to have lost my mind. I had a firewall setup with the wizard defaults and it worked just fine. Late a co-worker tried to get a ste to site vpn working and the internet access has been gone since. I just can't fine the problem. Can someone look at my config and see what is wrong?

Result of the command: "show run"

Pings go through and you get a reply. Thanks for you help!

ASA can't get to the internet HTTP but can ICMP.

Hi,

On a quick look I cant find any specific problem.

Provided that all your hosts are behind the "inside" interface?

You seem to have a lot of networks behind the "management" interface. Though your Management interface is configured with the "management-only" setting so it wont pass any traffic through it. It will only allow management connections to the actual interface.

Though it doesnt really make sense if you can ping hosts on the Internet but cant connect to them?

Is there a chance that there is some problem with DNS?

Give an example IP address of a host that cant connect to Internet.

You can also test firewall rules with command "packet-tracer"

packet-tracer input inside tcp 12345 1.2.3.4 80

Just as an example command. It will tell what the firewall would do to the above HTTP connection to IP 1.2.3.4

Thats the wierd part the packet trace is good. DNS is fine that was the first thing I checked. Its all just very odd.

When I ping it resolves to 8.8.8.8. All I'm trying to get to on the web is www.google.com or ipchicken.com.

This is baffling!

Thanks

Hi,

Can you take the output of a "packet-tracer" command using some source and destination IP address related to what you are actually testing and copy/paste the output here just to confirm that the ASA configuration isnt problematic.

You can also remove the "inspect http" if you want to test that but to be honest I have never run into problem with it.

OK problem found!! Obviously when Cox Cable shuts off service for billing the just shut off HTTP/HTTPS and leave ICMP and DNS working. This was the strangest problem ever. Thanks for all the help.
