Can you be more specific about the differences between the reported data in the two products? Note that MRTG will be giving the figures in bits/sec averaged over 5min windows, according to your config. So you may get a factor of 8 difference (if the other reports in bytes) or slight discrepancies (if they poll at different intervals) though the overall average/total will be the same. Also, you are not using SNMPv2, so you will get problems when you get to the 100Mbps rate or higher due to 32bit counter rollover. This is likely the problem. Try adding :::::2 (five colons and a 2) immediately after the IP address in the Target line. This directs MRTG to use SNMPv2 and the 64bit counters instead.
