Wonder if anyone can help me shed some light on this.
Background: I've got a client that, AT RANDOM TIMES, use up to 1gb internet per day. Have installed Netlimiter on PC's, removed PC's from network, changed router passwords, changed ISP passwords + DSL secure, disabled wireless on their NetGear DG834GUK, etc etc. Some days it's fine (100-150mb), other days not (500-1500 mb).
This weekend I logged into their PrePaid WebAfrica account, and saw they used 500mb on Saturday. They don't work on Saturdays, and only the Server is on. What is strange though, is that it's EXACTLY 250mb received, 250mb sent (ie, equal upload and download).
This morning I got a brainwave and checked the Firewall rules on the Netgear itself. It was set to allow ALL incoming traffic and direct it to the server. Removed that, and also copied the LOG. [EDIT: I see now it was sent to the Server's secondary Network card - but I changed the infrastructure around so that it's only on 1 Network card now, so that forward should have done nothing then. Ignore]
* Note that I removed the client's last two IP digits.
Question: Does any of that in the log look suspicious? I use LogMeIn to connect to their server - so that might explain some of the entries in the log? [EDIT: I cleared the log, and logged in via Logmein - nothing was logged - so assume it's not LogMeIn?
Is it possible that someone / something used their router as a relay of some sorts? And what does all these entries in the log mean? Can I check where these come from, and what the ports are used for?
Tx.
