Hello,

	I am using KA9Q (NOS) package as an IP gateway between
	two Ethernets, but I am experimenting a routing problem.
	This is the scene :

                            KA9Q                   IP/X25
	     Sun  Sun        PC              Sun-----------> world
	      |    |       |    |             |
	      --------------    ---------------
		138.82.2	139.82.1

	I have defined a default route in the configuration file, so
	all the hosts on the 139.82.2 side can reach the world. But,
	the problem is that the KA9Q gateway sends this route to
	both subnets, changing the default route of the hosts at the
	139.82.1 side, pointing it back to the KA9Q gateway !
        I don't want to add a route explicitly at every host of
	139.82.2 subnet, and want that KA9Q gateway continue to supply
	its routing table to both subnets (see the rip add commands below).

Any help/idea/suggestion would be GREAT ! Thanks in advance.
