As I read it, your routing table still doesn't have a route for the entire
loopback network, but does have a route for a single host on the loopback
network, namely localhost (aka 127.0.0.1). All loopback traffic except
stuff that is destined for 127.0.0.1 should go out to your default gateway
192.168.5.1.
Here's my routing table on my laptop (Slackware linux 8.1):
$ /sbin/route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth0
