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.

Why do you need to allow Windows traffic at all? (135 & 445) -- also, telnet (23)
highly unlikely to be necessary. Are you sure there's no spambot running on the
LAN?
 
It might be that the router have been compromised.

If you want better logging, then you'll need to use a dedicated firewall, such as Smoothwall. This will enable you to block all outgoing traffic (and incoming as well) except specified otherwise.

Check for proxy services on the other PC's - it might be that somebody have setup a nice proxy server for their own use.

And good luck.

It's not! Only thing that is setup now is SNMP and SNMP-TRAPS, as I installed PRTG Traffic Grapher this morning to help with this whole debacle, and had to create inbound and outbound rules.

Is it possible that someone Telnet's into the router, and opens up those ports? If I changed the router password - can they still Telnet in!?

How would I check for spambots?

Have tried Smoothwall before, wasn't successful. Should maybe give it a go again. Wanted it specifically for reporting purposes (User ABC at IP 192.168.0.123 used 10mb Today, 50mb last week and 250mb last month-type stuff), but couldn't get it working...
 
The fact that you reported identical usage on up/downloads is giving me reason to believe that a proxy server have been installed on one of the PC's - which means you have to view all of them as compromised.

As for the Smoothwall installation, best is to start with small steps. Get the basics working, then work your way upwards.

And do visit the forums if you're stuck, there's always somebody willing to help :)
 
Thanks for the responses TheLib.

Can't I disable Telnetting into the router from the WAN side? I've tried Telnetting into the router now, by going to cmd, telnet, and o 41.243.xx.xx but it says "Could not open connection to the host, on port 23: Connect failed". There's nothing on the log either? Even after enabling debug mode?

Smallaxe has me worried now that I see 135 and 443 is / was open, and that it became open just after port 23 (telnet) got logged.

Pls help!

bees, I know you said that your removed the Inbound rules, but you should ensure that your Inbound firewall is Enabled and set to block all incoming traffic - not just ALL except HTTP.
Also disable UPnP.

The majority your entries on the log were inbound Windows Shares (135 & 445) to PC's inside your network and Telnet (23) connections to the router (probably hacking attempts).
 
Thanks Pada,

I have blocked everything, but seems like its still allowing stuff to come through?

Where can I see where that IP comes from / to who it belongs to?

Have disabled UPnP now as well.

The router is using DDNS so that I don't have to LogMeIn into their server to access the router - should I disable that?
 
Here's more! Quite a few entries comes within the WebAfrica network (41.243.x.x), including the Telnet sessions - WHAT THE HELL!? Can someone PLEASE help me explain this...

Also, don't know how this Any(ALL) rule comes in there - have blocked everything (with logs).

Phoned WebAfrica now - not willing to help.

They can't see who is 41.243.115.84, 41.243.26.168 or 41.243.158.167. Just keep telling me that there is only 1 connection to their line port on their client code.

:(
 
Have updated the logs with more entries. Can no-one tell me what is going on? Would it help if I install another router at the client? Which router would you recommend?

Make sure that you didn't enable DMZ.

Btw, can you edit the default Inbound Firewall rule? Or did you just add a new one which must block & log all the incoming connections?

DMZ is disabled.

Nope, can't edit it. Have created a BLOCK ALL rule on Inbound Services with logging.

Only realise this now - those rule matches doesn't actually mean they got in - is it? Just that it matches the rule to Block the connection, and log it?

Damnit - wish I knew more about these things....
 
My guess is that it logs it even if it blocks the connection.

Have you looked at your usage reports yet?
 
Usages seems normal again, but what bothers me - it's fine for a while, then goes balls to the wall within a day.

They're on prepaid, so I'm just buying them 1gb at a time - so if they get compromised again, it's *only* 1gb down the drain...

Thanks for the help sofar Pada - will keep this thread updated if I find something.
