hardware requirements are mostly based on the amount of encrypted
packets you need to support. If it runs Linux, it can run libreswan.
We even have it running on the Lantronix XPORT PRo, which is an
embedded 32bit x86 nommu CPU with 16MB of RAM.

But we also support things like the Mellanox Innova 40Gbps IPsec.

For more "regular" IPsec traffic of up to 1gbps, regular PC hardware
is fine.

Note that for AWS, I personally found that the "hardware" specs seem
to be a bit overselling the actual performance.
