I'm Working in a mid-sized telco, and I'm in charge of network monitoring solutions. We have a custom monitoring system, that is using mostly SNMP to communicate with devices. The problem is that every once in a while, we need to add additional polling servers, and everytime we have to update 10k+ ACL's on each SNMP enabled device to add the new IP addresses. They cannot be predicted in advance, because servers are situated in different data centers, with different L3 connectivity.
This is hard work for our operations, and they're not happy with it.
My question: Is there any SNMP or UDP proxy that we can just install on one host, and forward every SNMP request to the devices through it?
