Hi all,
I wrote a module for Dynamic NAT.
My modules are hooked in PREROUTING and POSTROUTING.
I try to modify the destination ip address in PREROUTING and the
source ip address in POSTROUTING.
for example,
// PREROUTING
if ( iph->saddr == MY_DEFINE_IP)
iph->daddr = MY_HOST1;
// POSTROUTING
if ( iph->daddr == MY_HOST1;
iph->saddr = MY_LOCAL_IP;
But it seems not working.
First, in ip_forward, because of (skb->pkt_type != PACKET_HOST), the
packet will be dropped.
If I pass the check of skb->pkt_type, the packet do not send either.
Thanks for help!
