[afnog] how to block spam activity on my router cisco 2600

[Paul Ikanza]

Paul,

The router wouldn't generate this kind of traffic-at least I haven't
come across that so far. 
Maybe by referring to the Ethernet interface they meant something on
your network is generating the spam-I had a problem once with my
exchange 5.5 box that was not secured and was an open relay and
therefore being used for massive spamming.
You might have a similar problem-I think you need to check that you
network is secured. You may have to configure some access lists to that
effect too!

Cheers, Paul

Paul,
I think what works better is if you have a mailserver through which all
mail goes 
through. You can setup spam filters, virus scanners on this server. Your
router should 
only have an access-list that should only allow mail from that
mail-server and deny 
anything called smtp from any to any.

I hope you can begin this way.

Regards

David
