| I might be misunderstanding the issue here but I thought that PoE
| used the unused pairs in RJ45 wiring and so if the power doesn't
| get through the firewall then its a conductivity problem between
| the input and output sockets on the firewall and nothing to do with
| iptables or UDP etc. If this misses the problem all together then
| just quietly delete the email.
