Ip addresses from IP pool don't need to be from the same subnet as ARC's address is.
ARC's ip can be private while pool is public. You have to route ip pool to ARC's ip from your gateway router.

Just a note: If you have not configured ARC (but configured NMC), you can manage your arc through NMC.
Run HARM, in IP address put your NMC's address, and community - NMC's rw communiti + "@<arc-slot-num*1000>".
Example: (suppose you arc is in 16 slot, NMC's rw community is private) community will be private@16000.

Hi Kirti,

  To add the IP pool which users get assigned to when they dialup use
the "add ip pool POOL_NAME priority 1 INITIAL_POOL_ADDRESS <first ip
number> SIZE <number of ips>" command from the terminal interface ( have
no idea how to do this in HARM, but if you look in the help for pool you
should find it.

  The local IP address should be the IP address of your arc.  Your arc
(or both your arcs, if you are using more than 7 Hiper DSP cards) need
to have their own IP address which is on the same subnet as your IP pool
(it's a routing thing: using a private IP for the NMC is fine, but for
the ARC, if you use a private IP, you have to use a private IP pool.)  I
think you can probably get around this with some routing at your gateway
box, but for 1 or 2 IP's, I wouldn't bother.

Hello List:

I am almost done configuring a 3Com TC Chassis using Total Control Manager
as configuring tool. However I am struck at couple of last configuration
responses, as below:

1) HiPer ARC: What goes in "Local IP Address" field? Why is this IP
addresses needed? Is this IP address same as the IP address in NMC?

2) Where and how an IP addresses assigned to Dial-in users. My understanding
was that there is an entry in HiPer ARC, where a pool of IP addresses
entered for dial-in assignment. I have no found any such entry. When a
dial-in user connects to a HiPer DSP, an IP address is assigned. How and
where that IP address is obtained from?

Thanks.
