Unknown Datagram decoding problem!

[<CGhercoias () TWEC COM>]

Hello,

Starting last night my snort system have started to record these alerts.
177.1.0.x is our proxy-gateway and from this machine all these alerts
are going all over the place in the network.
Someone have seen these before? Is some kind of new exploit out there?
