SUMMARY: 240 Subnet /etc/netmasks problem

Thanks to Matt Harris and Marco Greene for their quick responses.

Matt had the solution:

/etc/netmasks will fix you up for startup if the system's ip is on that
subnet.  Otherwise, you need `route add -net 192.168.54.48 <gateway> netmask
255.255.255.240`

It only needed slight modification:

route add -net 192.168.54.48 -netmask 255.255.255.240 10.20.1.3


Thanks to everyone for their help,

Subject: 240 Subnet /etc/netmasks problem


First let me say that I checked the faqs, google, sunsolve, etc... It's
possible I missed something but I did look.

I need to configure a route on a system to reach a subnetted (netmask
255.255.255.240) network. I have tried a number of different settings in the
/etc/netmasks file but when I add the route for the network I invariably end
up creating a route to the class C and not the subnet.

These are a few attempted /etc/netmasks files.

First I tried the following format (based on past experience):
192.168.0.0     255.255.255.0
192.168.54.0    255.255.255.240
192.168.54.16   255.255.255.240
192.168.54.32   255.255.255.240
192.168.54.48   255.255.255.240

Then I tried the following as suggested on sunsolve:
192.168.54      255.255.255.240

This is the command I am using to add the route.
ptimbwm1# route add -net 192.168.54.48 10.20.1.3
add net 192.168.54.48: gateway 10.20.1.3

And this is what the route invariably looks like:
ptimbwm1# netstat -rn
[...]
192.168.54.0         10.20.1.3            UG        1      0  
[...]

Does anyone know what setting I should use in the /etc/netmasks file to have
the route for the subnet exclusively? I should add that I have changed the
IPs and they are in fact real Internet IPs, not private network IPs as shown
here.

Thanks in advance for your help,

-JohnF
