I set all the carp interfaces, both base and alias, to the 255.255.255.255 netmask as you suggested. This is my netstat now: ... 192.168.10.0/24 link#11 UC 0 0 vlan10 192.168.10.254 link#11 UHLW 2 0 vlan10 192.168.10.10 192.168.10.10 UH 0 0 carp10 192.168.10.11 192.168.10.11 UH 0 0 carp10 192.168.10.12 192.168.10.12 UH 0 0 carp10 ... As you see, the 192.168.10.0/24 is routed through the vlan10 interface, and this should be correct. As before, I can ping 192.168.10.10, but not 192.168.10.11 and above. Could this be a bug of carp with alias interfaces? Thanks again. Giulio.
