Your mail is pretty hard to understand.

DCOM uses DCE/RPC. DCE/RPC uses the endpoint mapper on port 135. The 
endpoint mapper mechanism will negotiate the "real" data transfer port 
(which could be any possible port AFAIK).

I don't know about a white paper telling about ports 6100 to 6200 only.

Basically if you want to use a port based filter with DCOM you're simply 
out of luck.
