ECP: SSDP gives me wrong IP after a while
I am playing with ECP and my Roku. When I use SSDP to discover my box, it gives me back the correct IP, but after a while the IP seems to have changed for the box and the SSDP call still gives me back...

For a remote developer with multiple users, how do you get past their firewall from outside the network? I don't think you cdan have a solution for a standard IP address using DHCP, because when they turn off a device and turn others on, there isn't a way to have that kind of control without using a dhcp reservation or disabling dhcp entirely. You'd probably really want a Roku with a built in modem and router into the same unit, which increases cost and complexity.
The problem (for the OP) is that the ssdp response from a Roku can be wrong (for instance: the Roku has a dhcp-provided address of 192.168.1.100, but tells you it's at .101 when you send the ssdp request). It's a Roku bug. It can be worked around (as you suggested) by setting dhcp reservation, so that the Roku never gets confused, but part of the reason Roku added the discovery protocol is so that network remotes can always find the Rokus on the local network, without needing static/reserved ip addresses.
