This is outdated; the lastest for wheezy is 3.2.68-1+deb7u1. But I don't see any fixes that seem related to this bug. > Arch: amd64 Linux > Desc: 3.2 for 64-bit PCs > > When using 'route -n' or 'ip route show' a certain /24 Route is > displayed, but does not have effect on the routing decision of the > kernel. > After removing the bogus route and setting it once again, everything > works as expected.

Only 192.168.18.1 is special. Were there any changes in routing to 192.168.18.1 or to 192.168.18.0/24, or was the route shown above present since boot?
