Routing

[Steve Dixon <steve dpn com>]

ok, ive done ip masq on a network with just one subnet (192.168.2.X). 
now im trying to do it for one that has 19.  there are routers at all of
the branches.  there is just one that i have to go
through(192.168.10.254) and my ip address is 192.168.10.2 and also the
external nic for the internet connection.  i can add a route for each of
the 19 subnets (192.168.X.X w/a gateway of 192.168.10.254).  is there an
easier way to do this other than an individual route for each of the
subnets?  then for the ip masq i would just do a:

/sbin/ipchains -A forward -j MASQ -s 192.168.X.0/24 -d 0.0.0.0/0 -i eth1

X being the individual subnets.  is that correct?

thanks,
