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?
There are two things to look at here:
a) Be sure that you have set the 'dhcp' option for your external interface in /etc/shorewall/interfaces.
b) Because your ISP is using RFC 1918 addresses within its infrastructure, you need to review Shorewall FAQ #14a (http://www.shorewall.net/FAQ.htm#faq14a).
