CNAT is quite affordable - under the new TEC/Netview licensing scheme, licensees
are entitled to CNAT - period. IT is trigegred to ship in a TEC purchase, among
other stuff.
For the record, when you license TEC, you are receiving Framework, TEC, TEC
adapters, Netview, CNAT, Tivoli Data Warehouse, and a limited Risk Manager
license.

Of course it does. Firewalls you can make holes in to allow snmp and icmp to
pass. However, if the things you are trying to monitor are natted, then the IP
information in the payload doesn't match the address in the header, so snmp
transactions become useless. To make it possible for Netview to manage NAT'd
devices using SNMP, you need CNAT. Comprehensive Network Address Translater. It
can do NATing, or it can do just the payload translation. It is fairly simple to
set up for just payload translation. It is a Tivoli product, and not expensive
the last I heard.
Cordially,

I have some devices on the external side of the firewall that need to be
monitored. My Netview machine has a NAT and can find the devices once placed in
the seedfile, but after the first polling cycle they become unreachable. Does
Netview have problems working through a firewall or dealing with NAT?
Thanks
