Fully Cisco on my end also... 803 as a NAT access-router at home, and
36xx devices from there on.

No idea here... I'm new to ECN; I did some lookups at work today but
didn't have time to finish reading on it....

doing NAT, since the IP header may need to be rewritten-- probably
without the ECN bits.
