I want to check some client OpenVPN TUN interfaces with MRTG running at my VPN server, so I have to specify their OID interface numbers in mrtg.cfg. The problem is, these numbers are dynamic, as they may change whenever OpenVPN restarts for any reason... so, how can I write stanzas such as
Target[somehostvpninterface] : ifInOctets.X&ifOutOctets.X:public@ <SOMEHOST.IP>
without wiring up the X interface number into cfg file? Or, is there any method to keep X from changing at the clients? Any hints appreciated!

You can take a look at ifrename(8).
