There are small, low-T= DP Intel systems for  up to ~$250 or so (including case) that use curr= ent generation Celerons with 4 2.5 GigE ports, and with the I/O bandwidth t= o easily support a full-on router at wirespeed on those ports.

The prob= lem with the low-end boards is that you need enough PCIe lanes to move pack= ets at 10 Gb/sec bidirectionally. The contained ARM chips may be fast enoug= h in principle, but the board and the PCIe are a bottleneck.

AliExpress sells such boards= and also barebones, but prices and specs vary.
