Re: [lwip-users] PPP and Ethernet at same time

lwIP's PPP runs as a netif, of which multiple are supported. Forwarding between 
networks (netifs with different network addresses) should be no problem.

TCP/UDP can bind to 0.0.0.0 to accept on all interfaces or on a specific IP 
address of one of the interfaces. No problem there.

I'm afraid I cannot tell you how hard it is to get PPP running as a netif with 
lwIP, since I've never done it. But once you have it running, the above 
features should also work.
