No. The FPGAs do not have direct access to the network. The FPGAs communicate via PCIe to the instance CPU, where the Enhanced Networking (ENA) drivers run. ENA provides a high-performance, low-latency virtualized network interface suitable for data movement to the F1 instance. See the EC2 ENA driver documentation for more details.

Any chance this is on the roadmap? I understand it’s a complicated feature to add, but I think this would add a lot of value to many users. I know there would be a decent number of users of it in AWS Tokyo. I believe you can do it while keeping the network safe by putting a switch in front of the card heavily restricting the activity of those network ports. Although my use-case requires production data I think if AWS was very worried about it messing up the network, there is still value even if it’s only an isolated network back to host ENI for testing designs.
