Help with a routing issue

[Leon Botes]

I have a freebsd 4.7 box at a client.
The box has an ip of 192.168.254.22
The default gateway is 192.168.254.1 which is the inside interface of the
gateway. The outside interface of the gateway is 196.25.37.18 and it also
has an alias of 196.25.37.19.

When i ping 196.25.37.18 from the clients box (192.168.254.22) i get this.
mmrserver# ping 196.25.37.18
PING 196.25.37.18 (196.25.37.18): 56 data bytes

When i ping 196.25.37.19 i get this.
mmrserver# ping 196.25.37.19
PING 196.25.37.19 (196.25.37.19): 56 data bytes
64 bytes from 196.25.37.19: icmp_seq=0 ttl=64 time=5.445 ms

64 bytes from 196.25.37.19: icmp_seq=2 ttl=64 time=5.226 ms

That is correct the way it should be.

My routes on the clients box look as follows:
mmrserver# netstat -rn

Can anyone help me with why the 196.25.37.18 ip is being redirected via
192.168.254.24?
