I think maybe I can verify that. I did the conversion with my windows
box, which in restrospect was a bad idea. since Then i have not been able
to get my firewall to grab an IP. I can put it in statically and pass
traffic. When I use pump and watch the logs this is what I see right
before a timeout:
xid: 0x63aabbdf4a rejected <-> 0x64aabbddcf
My suspicion is that this is their dhcp server rejecting my request on
what I can only assume is the MAC address of my NIC. although I cannot
find any decent documentation.
