Thanks for your answer, it's more clear to me now. Well, I want to keep the 10.0.0.0 subnet (If I can!). If I modify my routing table as follow : > > the gateway between the subnet and the localnet has the following > routing table: Destination Gateway Genmask Flags Metric Ref Use Iface 10.1.0.0 * 255.255.0.0 U 0 0 0 eth1 10.0.0.0 * 255.0.0.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo 0.0.0.0 10.0.0.1 0.0.0.0 UG 1 0 0 eth0 The subnet portion of the address has not all bits set to zeroes, so it should work, isn't it? Now the stations on 10.0.0.0 has the routing table: Destination Gateway Genmask Flags Metric Ref Use Iface 10.1.0.0 10.0.0.2 255.255.0.0 U 0 0 0 eth0 10.0.0.0 * 255.0.0.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo 0.0.0.0 10.0.0.1 0.0.0.0 UG 1 0 0 eth0 And on the subnet 10.1.0.0, we have : Destination Gateway Genmask Flags Metric Ref Use Iface 10.1.0.0 * 255.255.0.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo 0.0.0.0 10.1.0.1 0.0.0.0 UG 1 0 0 eth0 So normally, the subnet are Ok, but I can't ping across the gateway... Moreover, when I do a traceroute from a station in 10.0.0.0 to one in 10.1.0.0 and vice -versa, it doesn't reach the gateway... Is it normal?? Any idea? Excuse me if the questions are naive, but I'm a newbie in routing... ;-) Thx again Seb. - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to [EMAIL PROTECTED]
