This will 9use the reachable SNMPD to proxy requests to the unreachable SNMPD. 10 11## Example configuration 12 13We want to poll 'unreachable.example.com' via 14 15'hereweare.example.com'. Use the following config: 16 17On 'hereweare.example.com': 18 19``` 20 view all included .1 21 com2sec -Cn ctx_unreachable readonly <poller-ip> unreachable 22 access MyROGroup ctx_unreachable any noauth prefix all none none 23 proxy -Cn ctx_unreachable -v 2c -c private unreachable.example.com .1.3 24``` 25 26On 'unreachable.example.com': 27 28``` 29 view all included .1 80 30 com2sec readonly <hereweare.example.com ip address> private 31 group MyROGroup v1 readonly 32 group MyROGroup v2c readonly 33 group MyROGroup usm readonly 34 access MyROGroup "" any noauth exact all none none 35``` 36 37You can now poll community 'private' on 38'unreachable.example.com' via community 'unreachable' on host 39'hereweare.example.com'. Please note that requests on 40'unreachable.example.com' will be coming from 41'hereweare.example.com', not your poller. 42
