What do you want exactly?
(Slave mode for the second news server? -- see xrefslave in inn.conf)


> 1. Using Innfeed command through Channel mode, is it correct?
>   1.1 Does "Channel mode" supply incremental sync?

What do you call "incremental sync"?


>   1.2 If "Channel mode" doesn't supply incremental sync, we need to use Funnel-file mode to sync remote NNTP server, right? Is

See the newsfeeds(5) man page.  It is where you specify the format

No there isn't natively.


> You know some times people usually behind firewall, http request is the most popular way to access news server.

You could also run nnrpd on port 80...
