On reviewing the subject of my post, I think I should have used the word "Prevent" instead of "Restrict" - would have been clearer as to what I want to do...

First, please take a look at my topology diagram: http://s1096.photobucket.com/user/willdennis/media/testbed_topology_diagram.png.html My problem is with the "WANem VM" host. It is connected to the two LANs, and I want the "10-net" interface to get a specific IP assigned, as well as a default gateway (this is working.) The problem is, I want the other NIC to get an IP assigned (which is working), but, NO default gateway set for that NIC. So the state I want to end up with is: Eth0 ("10-net") -> specific IP address assigned, has default gateway set (same as all other hosts on that network that use DHCP) Eth1 ("20-net") -> pool IP address assigned, NO default gateway set (unlike the other hosts on this network that use DHCP, which all need a default gateway assigned) Right now, the eth1 on the WANem host IS getting a default gateway assigned, which leads to this host having two default paths out: Destination Gateway Genmask Flags Metric Ref Use Iface <netroutes redacted> 0.0.0.0 192.168.10.254 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 192.168.20.254 0.0.0.0 UG 0 0 0 eth1 This is causing a reachability problem with this host. Here are the active stanzas in dnsmasq.conf currently: interface=vl10-ovsbr0 interface=vl20-ovsbr0 bind-interfaces dhcp-range=vl10-ovsbr0,192.168.10.50,192.168.10.150,4h dhcp-range=vl20-ovsbr0,192.168.20.50,192.168.20.150,4h dhcp-host=52:54:00:d5:ee:4d,id:*,192.168.10.1 dhcp-mac=set:wanem-20,52:54:00:45:8c:6a dhcp-option=vl10-ovsbr0,3,192.168.10.254 dhcp-option=vl20-ovsbr0,3,192.168.20.254 dhcp-option=net:wanem-20,3 I'm sure it's a simple config change, but I cannot seem to figure it out... If someone could help me out here, I'd sure appreciate it...
