Let me paint the scenario...
I have a PIX 520 4.4(4) 128MB, unlimited connections with 3 interfaces (inside, outside and DMZ)
I use NAT, STATIC and CONDUIT.
My external interface is connected to a (Fujitsu)Verizon DSL modem.
All is working fine, except, the live IP which is mapped(using a STATIC) to my mail server's outside NIC which is connected to the DMZ intermittently fails. You can't ping it, although I can ping the internal IP of the NIC....
Any ideas will be greatly appreciated,
Hans
