You can either use the FreeBSD libalias library and do it from "user space" (works for PPP), or add back in the IP Filter bits to the FreeBSD TCP/IP stack that were removed when it was ported to eCos. The IP Filter method is probably more generally useful, as you can also implement firewall features.
