Debian – Static route in conflict with a route

debianroutestatic-routes

I have a route configured.

192.168.1.0/24 dev eth1  proto kernel  scope link  src 192.168.1.1

I'd like to add a static route to pass traffic destined for 192.168.1.51 via a load balancer's redundant virtual interface at 192.168.1.2.

ip route add 192.168.1.51 mask 255.255.255.255 via 192.168.1.2

When I try to add the static route I get this error.

Error: either "to" is duplicate or "default" is garbage."

Is there a way around this?

Regards

Ossan

Does ip route add 192.168.1.51/32 via 192.168.1.2 accomplish what you need?

Problem linking two Cisco routers with a static route

Because the external interface on R2 is on the same LAN as the clients on 192.168.1.0/24, you'd need a route on each client on 192.168.1.0/24 to route to 192.168.2.0/24 via 192.168.1.2. That should do the trick (assuming R2 is routing, not NAT, and has no firewall.)

If I were you, I'd throw the link between the two routers into its own administrative VLAN and then you could route through this VLAN.

Windows – Static route for entire octet or by host name

You can "wildcard" IP addresses by just changing the netmask:

route add 192.0.2.0 mask 255.255.255.0 <router>

There's no way to route to a hostname, because names are handled at a higher level of the network stack.
