# SNMP Proxy

If you have machines that you want to monitor but are not reachable directly, you can use [SNMPD Proxy](http://www.net-snmp.org/wiki/index.php/Snmpd_proxy). This will use the reachable SNMPD to proxy requests to the unreachable SNMPD.

## Example configuration
We want to poll ```unreachable.example.com``` via ```hereweare.example.com```. Use the following config:

On ```hereweare.example.com```:
```
        view all included .1
        com2sec -Cn ctx_unreachable readonly <poller-ip> unreachable
        access MyROGroup ctx_unreachable any noauth prefix all none none
        proxy -Cn ctx_unreachable -v 2c -c private unreachable.example.com  .1.3
```

On ```unreachable.example.com```:
```
        view all included .1                               80
        com2sec readonly <hereweare.example.com ip address> private
        group MyROGroup v1 readonly
        group MyROGroup v2c readonly
        group MyROGroup usm readonly
        access MyROGroup "" any noauth exact all none none
```


You can now poll community ```private``` on ```unreachable.example.com``` via community ```unreachable``` on host ```hereweare.example.com```. Please note that requests on ```unreachable.example.com``` will be coming from ```hereweare.example.com```, not your poller.
