will for starters you have one side tagged ( 802.1q ) and the cisco access mode.

Either change the cisco to a trunk mode ( 802.1q )

config term

int gi 0/1

no switchport access vlan 300

switch mode trunk

switch trunk allow vlan 300

end

or remove the vlan interface and make the FGT access mode.

Depending on cisco switch type you have to set the encapsulation also.

e.g ( check the capabilities of the interface 1st )

show int gi 0/1 cap

Now we can set the trunk encapsulation

config term

int gi 0/1

switch trunk encapsulation 802.1q

do copy runn start

end
