My downloads bandwidth on the 30D maxes at 10mbs while my internet speeds are at 75mbs. I plug the laptop directly to the model and i get full speeds. Anyone have any suggestions?

    From the FGT CLI, perform a "diag hardware deviceinfo nic <wan port>" on your WAN connection and check what speed your fgt is connecting at.  If your ISP connection is 75 Mbps then the duplex/speed should be at least 100 Full duplex (or higher).    If you see any errors from the diag output (above) it's possible you have duplex/speed mismatch.

     

    Keep in mind if you have any UTM/IPS features enabled on the fgt (firewall polices), it will "slow" your connection down somewhat.

    If the FortiGate does not much else, i doubt IPS/UTM should have this impact. It's advertised with 150Mbps IPS throughput. I'm not assuming 100% here, but 10 vs 150 would far too little.

     

    If you start multiple downloads simultaneous, do you exceed the 10Mbps? I have experienced before that while a single connection is somehow limited to 10Mbps on 30D multiple connections/sessions improve the overall situation.
