So, to summarise, it looks like cfgmaker is offsetting the IP addresses by one each time?

Can you let us know which version of MRTG (and therefore the version of cfgmaker) you are using, and update to the latest (2.16.4) if it’s a particularly old one?

Also, have you tried a 'snmpwalk -v2c -c public 192.168.199.1 interfaces' to see what you get?  Possibly the SNMP agent is reporting the wrong data, in which case try restarting it.
