Hi all,
I’m would like to understand if FreeRTOS is able to manage IP aliasing in connection to LWiP.
My aim is to have more than 1 IP address assigned to my ethernet port port on a Cortex M4/M7/M33 uC
Hi @Lps,
Welcome to the FreeRTOS community.
In FreeRTOS, we have our FreeRTOS-plus-TCP stack which is a well tested code using unit-tests, CBMC(Memory safety proofs) and Protocol tests. In this stack we support having multiple endpoints(IPv4 or IPv6) on the same physical interface. And each of the endpoints can have a different ip-address.
This will mostly serve the ip alias functionality that you are looking for.
This page describes multiple interfaces and multiple endpoints - FreeRTOS-Plus-TCP Multiple Interfaces - FreeRTOS.
Thank you @Shub .
I was wandering if there is someone who did it using LWiP.
I really don’t know how much effort does the porting of my application to FreeRTOS-plus-TCP takes…
You are likely to get better response on LWIP mailing list.
Same socket interface APIs are used in both , hence from application point of view there will be no difference.
Good feedback, thank you
I would not even bother with LWIP !
Why would you even consider it when the FreeRTOS TCP package is mature and reliable and capable and fully featured integrated into FreeRTOS?>
LWIP is a P-O-S… It is something you use on a constrained 8 bit microprocessor in the 1990s
