lwIP NAT componenent
If you want to use lwIP NAT componenent, please define LWIP_USING_NAT in rtconfig.h.
In this case the network 213.129.231.168/29 is nat'ed when packets are sent to the destination network 10.0.0.0/24 (untypical example - most users will have the other way around).
Use following code to add a NAT entry:
ip_nat_entry_t nat_entry;
nat_entry.out_if = (struct netif *)&emac_if1; nat_entry.in_if = (struct netif *)&emac_if2; IP4_ADDR(&nat_entry.source_net, 213, 129, 231, 168); IP4_ADDR(&nat_entry.source_netmask, 255, 255, 255, 248); IP4_ADDR(&nat_entry.dest_net, 10, 0, 0, 0); IP4_ADDR(&nat_entry.source_netmask, 255, 0, 0, 0); ip_nat_add(&_nat_entry);
