Dear ALL,

I have an ASA 5510  sw release 8.0(2) and you can find configuration at the end of this document.

I have connected a LAN (PCs and Servers) of a customer to the INSIDE , and everything is working properly.

But I have to connect another customer which computers are behind an ISA Server, and troubles get started.

(ISA Sever has been conencted to DMZ , and INSIDE too for test purpose, but the same troubles occour)

Some time it doesn't run, or when it start running properly it stops run after a period of time (diffferent periods time after time)

Please, anyone of you could give any suggest about it?

                                       Regards

                                       Alberto Brivio
