Hi,
table ip nat {
chain prerouting {
type nat hook prerouting priority 0;
tcp dport 222 redirect :22
}
chain postrouting {
type nat hook postrouting priority 0;
}
}
With the above rules, data[priv->sreg_proto_min].data[0] has value
0x160000 instead of 0x16 on powerpc (Big Endian byte order)
Due to this, mr.range[0].min.all gets assigned value 0 instead of 22.
Below patch fixes it, but it is maybe not the proper way to fix it, so I
let it up to you.
