[Sderby] Power over Ethernet

[Mike Hemstock]

Folks,

I'm having trouble getting PoE to work through a firewall.  The device
will not power up using PoE.  If I put a adapter directly into it I can
see data traveling through the firewall, but not power.  I have ran
tcpdump and there appears to be no power getting through.  I assume there
must be a way to create rules to allow power through the firewall, but I
have grepped the iptables man page and searched on google and can't find
anything.  I tried doing iptables -F to flush the rules and allow anything
through, but the firewall is still not passing power.  Does anyone know if
there are any specific rules to enable power through iptables for Power
over Ethernet enabled devices?  I assume Power over Ethernet travels via
UDP?  Does anyone know what port its on?

Mike.
