One Workstation with No Browser Internet But Can Reach via TeamViewer

Hey guys,

Have some weirdness going on that I wanted to see if I could get some ideas for. I am the network engineer for a small company and recently deployed a new Fortigate in one of our branch offices.

The FortiGate is up and running and has successful connections to the internet via our ISP and is allocating DHCP addresses and DNS for our office workstations. Everything is up and running as normal, except for one workstation.

This station for whatever reason cannot access the internet through a browser or email applications, but we have a TeamViewer style application that is used over the internet and this is working just fine.

I can ping our internal servers and resources but anything external is not reachable, only for this one workstation. All the others in the office are working just fine and they are all using the same Fortigate device. This station is supposed to be directly connected to our Fortigate but I have not actually been to this office so I don’t know what the physical connection and setup is like.

Any thoughts or ideas? I am pretty puzzled here. Imagining there may be some sort of DNS issue that’s going on but just not sure what since the station is able to ping our DNS server and even RDP to other servers on the network.

Thanks for any advice!
