I got some success with PF and the static-port keyword: nat on pppoe0 inet from 10.0.0.0/24 -> ( pppoe0:0 ) static-port The Nintendo Switch reports a B grade. However, I do not understand how source ports can be preserved on a 1:n IP addresses mapping, I suspect they get preserved most of the time? The setup has a setback: from time to time, all NAT-ed traffic gets hang for several seconds. Is there a static-port equivalent on IPfilter or NPF? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz m...@netbsd.org
