I also requested Telstra look into the 172.20.18.55 port 67 issue I have
logged similar packet counts with IPCOP 1.4.10 over the duration others here
have seen i.e. the last few months at least and after 4 emails and 11 days
with no response this is the reply I received today, it seems to be a
interestering way of attempting to explain whats going on.? :-) but I don't
quite believe it myself.
Discussion Thread
My firewall has been logging for some time a significant number of packets
unrelated to either my paradise.Net connection or my internal network. The
packets appear to be coming from a private address range 172.20.18.55 port
67 (Bootps) internal to telstra as a traceroute would indicate below. At
the rate they are being received approx 10,000 per day I am concerned that
this is adding to my usage unfairly. Can you please confirm if this matter
is being investigated and or if a resolution is forth coming.

Response (Helpdesk)
Thank you for contacting us.
After investigating this on your behalf I have discovered that the packets
come from our Customer Help modem interface which we use for diagnostics and
troubleshooting. I think that in the time that you checked the packets, one
of our technicians was pinging your internal IP address from here; as this
is internal traffic you will not be charged for this.
Should you need any further assistance, or if this does not solve your
query, please let us know.
Kind Regards,
Ruth

Well something has changed in the last couple days.
My Activity light is now blinking, rather than being solid-on for as long as
I watch it.
Anyone know anything more?
