Hello,

I'm trying to figure out why I have to reset my cable STB and Bering box
when my IP changes.
I read this on the help site for UK cable internet ISPs.

"You should use the private IP address for the UBR, for instance, when
configuring firewalls to permit the UBR to send to your PC"

"The PC [My Bering box] transmits a broadcast calling for a DHCP server
to respond. This is picked up by the gateway-UBR, which is a DHCP Relay
Agent (see RFC 2131), and passed to the real DHCP server elsewhere in
the ISP's network. The reply from the DHCP server also has to be
broadcast back into the sub-net of the calling PC. The gateway-UBR
therefore has to broadcast DHCP responses into the CATV network in the
hope that the calling PC will recognise the reply intended for it. As a
side-effect, every customer PC on the CATV network will also receive
these DHCP broadcast replies, all of which will appear to emanate from
the UBR's private IP address 10.xxx.xxx.1 or 172.xx.xxx.254, directed to
the PC's DHCP client port."

It's from this address that DCHP replies are sent to my Bering box. This
is received by pump, yes?

Does pump already handle letting DHCP replies through shorewall? Or will
I have to configure this myself?

Cheers,

James
