What is "CMTS"? Apart from that and the fact that "Other PC" means 6 
different interfaces serving my other 6 (internal) networks, you seems 
to be spot on.

Just to make it absolutely clear - the "Other PCs" addresses are of no 
concern to me at all - as they form part of my (internal) networks I 
have full control over what happens there. The only problem I have is 
with the renewal of the public IP address given by the provider, that's all.
