reading the first post more carefully, I see that the netmask conditional is also the problem in the original report:
new_subnet_mask='255.255.255.128' therefore the host route to the gateway is not added because the netmask is not 255.255.255.0 While waiting for this bug report to be addressed, a suggested solution is to add a dhclient exit-hook: create a file "gateway" in /etc/dhcp3/dhclient-exit-hooks.d, containing this text: for router in $new_routers; do route add -host $router dev $interface route add default dev $interface gw $router $metric_arg done -- dhcp fails for gateway on different subnet https://bugs.launchpad.net/bugs/139217 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
