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);
