We need a way to monitor devices behind a firewall without compromising our DMZ. We have already looked into adding expansion pollers, and opening ports in our firewalls to allow for Solarwinds polling. We have done some research and found a couple of SNMP proxy products called SimpleSNMPProxy and MGSOFT Proxy. Has anyone used these products? If so, what are your experiences with the products? Is there another way of doing this?
