Are you able to ping 193.xxx.xxx.121 from the ASA?

No, I can't ping the default gatway from ASA,

ASA Version 8.2(5) - no internet access

Collin Clark — Tue, 21 Jan 2014 19:57:49 GMT

That would be the first thing to resolve. If you have ICMP turned off, see if the gateway is in your ARP table.

Collin Clark — Wed, 22 Jan 2014 14:21:02 GMT

There is not an entry in the ARP table. Two things to try. From the ASA can you try and ping ISPGateway and then immediately show arp and see if there is an entry? If there is not, is there a way to check that the internet connection is working e.g. connect a PC to it?

Re: ASA Version 8.2(5) - no internet access

ionutiordachescu — Thu, 23 Jan 2014 13:52:49 GMT

I conected the ASA behind a router and configured it with dhcp outside -> works perfectly. Changed the configuration to fixed IP and connect it directly to ISP cable -> not working. The ISP says it's not storring mac addresses (which I actualy checked by configuring and connecting 2 different routers -> works fine). I even changed the firmware on the ASA (upgraded and downgraded it)... no connection.

Thank you anyway for your help, I'll update the thread incase I come up with a solution.

Best regards,

Ionut
