Torch it and see what the SRC and DST ports are.

Subject: [AFMUG] Mikrotik Possibly Compromised

So I've noticed some strange behavior on my home connection (Comcast).  The 
Mikrotik that I am using shows a constant Tx on the WAN port of around 3-5Mbps 
and between 200-300pps, Rx is just a few kbps.  This activity appears to be 
strictly on the WAN port.  If I disable a firewall rule that accepts input, the 
activity ceases - but devices behind the router lose connectivity.

Any ideas?  I've got all IP services disabled except winbox, which is 
restricted to my local network.
