However, it does very happily do so to the local network. While this is probably not an issue for many, I do not have any decently powered server at home, only a rented one outside to do my network statistics. + +To overcome the issue, I needed to get my OpenWRT -router to bounce the SNMP packages to the modem, and relay replies back. And while it is seemingly possible with net-snmp snmpd, the configuration is far from straightforward and the OpenWRT packages seem to be lacking in that regard. + +Hence I wrote my very own, very simple, proxy daemon. It is not smart at all and simply sends SNMP replies back to the last one to make a request. But it works for my purposes.
