[suse-security] Martian addresses attempts



I have a network pf Windows PC's which has all of a sudden started to run 
incredibly slowly, the PC's sometimes simply can't log on at all.

When I run the 'iptraf' programme it appears that traffic is trying to get to 
ip addresses that simply aren't on the local network. The local network is 
192.168.2. and all addresses should be in this range. Here is an example of a 
few log entries.

48 bytes; from 192.168.2.27:2190 to 192.168.91.211:445; first packet (SYN)
48 bytes; from 192.168.2.27:2191 to 192.168.172.38:445; first packet (SYN)
48 bytes; from 192.168.2.27:2192 to 192.168.168.5:445; first packet (SYN)
48 bytes; from 192.168.2.27:2193 to 192.168.51.177:445; first packet (SYN)
48 bytes; from 192.168.2.27:2194 to 192.168.250.226:445; first packet (SYN)
48 bytes; from 192.168.2.27:2195 to 192.168.23.69:445; first packet (SYN)

Anyone got any idea what could be causing this.

Regards
Andy
