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?
