Hi Marco, Taken from inet(4): IPCTL_FASTFORWARDING (ip.fastforwarding) Boolean: enable/disable the use of fast IP forwarding code. Defaults to off. When fast forwarding is enabled, IP packets are for-warded directly to the appropriate network inter-face with a minimal validity checking, which greatly improves the throughput. On the other hand, they bypass the standard procedures, such as IP option processing and ipfirewall(4) checking. It is not guaranteed that every packet will be fast-forwarded. I think the bigger issue is that it bypasses firewall checks, so make sure if you use this, not use it on a firewall. -SLM > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi! > > Which is the different between net.inet.ip.forwarding and > net.inet.ip.fastforwarding?
