Strange LAN "problem"

I have the following problem while trying to ping another machine inside my LAN:

$ ping mb13
PING mb13 (192.168.2.10): 56 data bytes
36 bytes from cwifi (192.168.2.1): Redirect Network(New addr: 192.168.2.10)
Vr HL TOS Len ID Flg off TTL Pro cks Src Dst
4 5 00 0054 a525 0 0000 3f 01 5123 192.168.2.6 192.168.2.10

I am trying to solve it – I use a Cisco 877W.

More info to come…
