7. m0n0wall

M0n0wall, a very strange software name, M0n0wall is based on the performance and stability of the FreeBSD kernel (currently based on 4.11, may be based on 6.x in the future) embedded firewall system.

M0n0wall has very low hardware requirements, 486 chip, 32M memory (generally recommended 64M), 8M hard disk (it can be used), plus network card (two, three DMZ support) Working properly and having very good data bearing capacity. The system does not use the external storage switch system, so the external memory such as the hard disk is only used when the system boots. After the loading is completed, the external storage is no longer needed, so the FLASH electronic disk (including the CF card transfer) can also be used as the system medium. This can achieve a very high reliability, because the FLASH media is slightly slower than the hard disk access speed, so a little sacrificed start time. For Pentium-class hardware configurations, the typical boot time is less than 1 minute.
