Hi Steve,
Pretty interesting stuff! So my standard advice for DHCP related problem
for cable modems will now enclude enabling a ICMP Ping Query filter the
DHCP server addresses used by the ISP.
Thanks!

Hi folks,
Just learn't something that may or may not apply to a lot of you who
can't renew dhcp leases on your cable modems or dsl routers.
I was speaking to a techie I met here in Bermuda today, and found out he
used to work in the cable modem support group for NTL in the UK. I don't
remember why it came up but the fact that some people (NTL), can have
problems with their lease renewal through isa stemmed from the dhcp
server not getting a ping reply from the modem. Apparently a lot of
ISP's servers don't renew the leases if they don't get a ping response.
So if you allow ping responses it may solve the problem. Must be worth a
try for all you people out there that can't renew.
