You can only stand pissing into the wind for so long! Nice fun investigating things we take for granted like ARP but more important things to do. 

I'll let you know when everything is built and I can do some more testing. A have a range of gigabit NICs to try in this new server.

As I said earlier in the thread this is not a UmTRX issue thankfully.
