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.

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. On Tue, 2003-09-16 at 18:44, Kirti S. Bajwa wrote:

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. ISN Support Staff wrote:

Can someone point to or send me some example filters for ARC? I would like to filter for the MSBlast worm at the modem pool. Thanks, Wayne Barber Coastal Telco Services
This filter will look like this one: #filter IP: 001 AND src-addr = 0.0.0.0/0; 002 AND dst-addr = <ip-addr>/<prefix>; 003 REJECT udp-dst-port = 69; 004 AND src-addr = 0.0.0.0/0; 005 AND dst-addr = <ip-addr>/<prefix>; 006 REJECT tcp-dst-port = 4444; 007 AND src-addr = 0.0.0.0/0; 008 AND dst-addr = <ip-addr>/<prefix>; 009 REJECT tcp-dst-port = 135; where <ip-addr>/<prefix> - is your ip-address pool. For more information read HiPer ARC Product Reference. You have to upload this filter file to arc using tftp. Wayne Barber wrote:
