FortiClient Blocked Our Company Web Sites

[grafilife]

I have a problem on my iMac. Last week we started remote bc covid-2019 :( Our company it team sended an application (Forticlient) for VPN and i installed. After 2 days they said me unistall forticlient and use your regular network. Than my mac blocked all our company ip adress.

I tried many different way;

-Dns flush

-Different VPN Server

-Apple Technial Team phone and remote support (yes they didn't fix my problem)

- Local DNS Clear (sudo killall -HUP mDNSResponder)

-Install and Unistall forticlient

But anyway didn't solve my problem.

Today i tried to edit my hosts file. I added " 194.36.160.75 mail.tmgrup.com.tr " this line on my hosts file and it will be opened. But our company has a lot of ip adress, a lot of website and i don't know all ip adress.

And than i tried change hosts file with new. But this way didn't work.

So anybody saw this error before? How can i solve my problem?
