will "NAT for lwIP" work with DHCP address mode?

[bandu]

Hi,

 

will "NAT for lwIP" work with DHCP address mode?

 

Is there any example code available with "NAT for lwIP" source?

 

thank you very much,

Assuming you mean "will lwIP work with an IP address that is given by a
NAT server", yes.

What exactly do you mean with "NAT for lwIP"? There has been code for
that around and there is a task for this on savannah (task #7506: NAT
support for lwIP). However, I assume both aren't used widely and I do
not know of any example code for it.

For it to work with DHCP, I guess NAT will have to be initialized after
the DHCP client got an address from the server (and thus the netif is
set up)?

Hi Kieran,

 

I found http://www.sm.luth.se/~conny/nat/index.html (NAT for lwIP).

 

I just want to find out what is that for.

Am I right in thinking that implementation will enable my device to be able to accept connection from device with different subnets?

 

I understand that "NAT for lwIP" is not part of LWIP. But just wish some one might know what is that for.

 

regards,

 

Bandu

I would try contacting the author:

http://www.sm.luth.se/~conny/index.html

but as the code seems to be about 6 years old, I wouldn't expect it to
"just work" - you'll almost certainly have to update it to work with a
current version of lwIP at least.
