I tried the following:
# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
131.181.144.3   0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
0.0.0.0         131.181.144.3   0.0.0.0         UG    0      0        0 ppp0

Then I did:
# route add -net 131.181.0.0 netmask 255.255.0.0 ppp0
# route del default
# route add default gw 131.181.142.1

# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
131.181.144.3   0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
131.181.0.0     0.0.0.0         255.255.0.0     U     0      0        0 ppp0
0.0.0.0         131.181.142.1   0.0.0.0         UG    0      0        0 ppp0

But still no worky!  I can see all the web pages on qut's network but
nothing outside.

Thanks.
