Solarwinds and NAT

virgilv

Can anyone address this question for me?

Many of the network mgmt tools (OpenView, CA Unicenter, etc.) do not work well in a NAT environment; i.e. if you begin discovery of nat'ed addresses, followed by snmp polling, you run into issues because the software now wants to use the IP addresses that were discovered in the SNMP poll.

I need an application that you can configure to keep the nat'ed addresses as a polling reference, but still use snmp to do your monitoring.

Can Solarwinds do this?

I think I understand the question you're asking.

SW can poll any device based on an arbitary IP address. If that address is a public IP like 223.4.4.1 which is NAT'd to 10.1.1.1 internally, SW will still go after an poll the public IP. It doesn't change the address it's going to poll unless you tell it otherwise.

Polling and SNMP monitoring use the same address in all instances. If you need to keep a separate record of what the internal address is, you can use a custom property.
