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
