VPN Tunneling in Forticlient

the only way on your side would be to manually modify your routing table after connecting the vpn but that would require you to know the subnets or hosts by ip you need to connect to at your university.

the only other way would be split tunneling but that has to be enabled on the opposite "end" of your VPN, so cannot be done by you.

Hello, 

Basically on your side there is not much you can do if all your traffic is being forwarded to the VPN. As previously said by sw2090 the solution would be split tunneling to be implemented in the FW gateway you are connecting to so for  X subnets you use VPN and for the rest you use your local network.
