EPB issue

I was having this issue with EPB earlier today:

james@computron:~$ time sudo ifup eth0
Internet Systems Consortium DHCP Client V3.1.3

Any thoughts on what may have been going on?  I thought it was odd that it
took so long for me to get an address (waiting after DHCPREQUEST sent each
time), and that the DHCPOFFERs came from two different addresses (x.x.x.2
and x.x.x.3).

I've been having DHCP problems with EPB for about a month now... my lease
will expire and I'll have to shut the port to them to reset the connection
before I can get a new lease, which of course is never the same as the last
one now...
