I'm sure, the problem is not a big one, however I'm stuck for now.
I managed to configure an ASA 5505 under home circumstances, with ADSL internet connection. All went smooth, I could rease the internet, and could reach the device from the internet.
The device is deployed now in a server park, with internet connection through a fixed IP and the first hop is a switch of the ISP.
The other side is a small LAN.
I can remotely manage the device, even port forwarding works to LAN, however there is no LAN communication with the WAN. I cannot ping and/or reach anything outside.
I added one static route on the outside, pointing to my ISP switch.
On the LAN I gave the inside leg of the ASA as the default gateway.
Could someone give me some clue where to proceed?
Thank you in advance!
