DD-WRT v2.3 or earlier

Do following steps to add your DD-WRTv23 for monitoring:

  1. Prerequisites
    • Public IP on Your DDWRT box or configured port forwarding so that snmp is accessible from odmon.com servers
    • DDWRTv24 with SNMP service (std or greater release)

     
  2. Enable SNMP service. Login to ddwrt web panel, go to Administration -> Services and enable SNMP service. Set RO community to your secret string (it will be kind of a password).
    You might also set name for the device. All other fields are not mandatory. Click 'Apply settings' what

  3.  
  4. Enable odmon.com queries. Go to 'Administration' > 'Diagnostics' and paste command
    /usr/sbin/iptables -I INPUT 1 -p udp --dport 161 -s 188.124.160.10 -j logaccept
    and click 'Save firewall'.
    If you have DMZ enabled, please do the following: go to 'NAT/QoS' > 'Port Forwarding' and add following rule:
    App: snmp; Port from: 161; Protocol: UDP; IP Address: LAN or WAN ip of the router; Port to: 161; Enabled: Yes. Click Save and Apply

    This will add entry to Your firewall, which allows odmon.com pollers to read snmp data required for monitoring.
