Perhaps I' ve not been clear enough.
I have several Fortigate 50B units - we use them for all of our customers and have at least a couple on the shelf at any given time.
I have set up the failed unit and a brand new unit ' on the bench' and exeuted a factory reset on both (execute factoryreset).
The new unit responds exactly as it should - ICMP and HTTP on the LAN interface at 192.168.1.99. Also, I can (as expected) " execute ping <test_pc>" just fine.
The failed unit exibits none of this behavior - I can' t access via ICMP or HTTP on the LAN interface, I can' t ping outward to the test PC, etc. On the outside chance that the factory reset somehow failed, I' ve done a diff on the configs between the two and they are identical.
There is also no response on the WAN side - i.e. if I set the wan1 interface to DHCP on both units, the new unit will execute the expected DHCP broadcast request and grab an IP. The failed unit does not even send out the broadcast.
However, both the lan and wan ports perform the low level phy speed negotiations exactly as expected - so the ports are ' working' at least at the hardware level.
The three LAN ports and wan1 are two completely seperate mac/phy - so the chances of BOTH failing at the same time from a hardware perspective is extremely low.
This is a FortiOS issue related to it' s licence expiring.
I will try to reload factory firmware via the tftp bootstrap process (which would be before FortiOS loads - so hopefully the lan mac/phy comes up OK).
However, I would appreciate if someone could post the console firmware upload process (xmodem) just in case.
BTW, I have lots of Fortigate hardware that is inside of contract - it' s just this one unit that has ' expired' (which by the way was the first " lab" unit that we purchased for evaluation). What concerns me is that we' ve only recently switched to Fortigate from a compeditive product line and I have a significant number of units in the feild coming up on their ' expiration date' . I am certain that at least some customers will not choose to continue with a service contract. If these things turn into bricks ' by design' when they' ve not been registered for a year, then I have a very serious problem on my hands.
