Thanks for your reply.
I can not remember what kind of setting I made, maybe just add new account, definetly no firewall rules applied.
when you use the console to execute a factory reset, you know what I mean, Factory reset means nothing applied, you should connect to the 192.168.99.
nothing to do with my configurations, just factory default!! dont suspect my experince in setting IP MASK,cabling.
But infact you can not ping from console to outside, you can not ping from outside to the interface. you also can switch to dhcp mode ,and get ip address from dhcp server but same message: network unreachable....
Everybody told me use TFTP, network unreachable how can you connect to TFTP server.
Strange things : I used mode dhcp, the fortigate can get the ip address from my dhcp server, but still can not ping in/out. 1 time I can get in the interface, when I move back to server room, power on/off, no access again.
when I tried to access interface, no any rules applied,no any special setting except ip address, netmask.
Again, I tried reset to default more than 30 times. suddenly I can access the interface, then I updated the firmware to MR7. now some user compain about the SSL-VPN, one user complain about his voip logon/off every 20 mins, I applied a ticket but 3 days no tech responsed.
We paid $800 for 2 year contract include hardware,firmware,antivirus......
Honestly Fortinet service really sucks. I am thinking about switching to different company when 2 weeks later old contracts expire.
