Vyatta static routing does not correctly route to next hop

Question

I configured static route using Vyatta like following:

set protocols static route 192.168.1.0/24 next-hop 10.100.0.204

But a packet which destination is 192.168.1.10 is not routed to 10.100.0.204.

vyatta@vyatta# traceroute 192.168.1.10
traceroute to 192.168.1.10 (192.168.1.10), 30 hops max, 60 byte packets
 1  * * *
 2  * * *
 3  * * *
 4  * * *
 5  * * *
 6  * * *
 7  * * *
 8  * * *
 9  * * *
10  * * *
11  * * *
12  * * *
13  * * *
14  * * *
15  * * *
16  * * *^C
[edit]

It seems that the routing table is correct:

vyatta@vyatta# ip route
default via 10.0.1.1 dev eth0  proto zebra
10.0.1.0/24 dev eth0  proto kernel  scope link  src 10.0.1.5
10.100.0.101 dev pptp1  proto kernel  scope link  src 10.255.254.0
10.100.0.102 dev pptp3  proto kernel  scope link  src 10.255.254.0
10.100.0.200 dev pptp0  proto kernel  scope link  src 10.255.254.0
10.100.0.204 dev pptp2  proto kernel  scope link  src 10.255.254.0
127.0.0.0/8 dev lo  proto kernel  scope link  src 127.0.0.1
192.168.1.0/24 via 10.100.0.204 dev pptp2  proto zebra

Strangely, it works correctly if next-hop is set to 10.100.0.200:

vyatta@vyatta# traceroute 192.168.1.10 traceroute to 192.168.1.10 (192.168.1.10), 30 hops max, 60 byte packets 1 10.100.0.200 (10.100.0.200) 7.524 ms 7.368 ms 7.590 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 *^C [edit]

Please tell me where I misconfigured.

Edit:

My network architecture is following:

enter image description here

I'm running Vagrant on Mac OS X machine(#1). Eventually I want to let Mac OS X(#3) access Vagrant VM(192.168.1.10) via VPN. The VPN connection is no problem.

Current Vyatta configuration

VPN:

vyatta@vyatta# show vpn
 pptp {
     remote-access {
         authentication {
             local-users {
                 ...
             }
             mode local
         }
         client-ip-pool {
             start 10.100.0.1
             stop 10.100.0.255
         }
         dns-servers {
             server-1 10.0.1.185
             server-2 10.0.1.162
         }
         outside-address 10.0.1.5
     }
 }

It can reach to Mac hosts but can't reach to Vagrant VM.

We need more information to help. What is at 10.100.0.204? What is at 10.100.0.200? Do you have access to either of those devices? Where is 192.168.1.0 connected? — Ron Trunk, Aug 24 '14 at 11:32
Keep in mind with that static route after the lookup to forward the traffic the router must find the Interface to physically forward the traffic. If the router cannot find which link has that next hop 10.100.0.204. it will not be able to forward the traffic. Please make sure you can ping that next hop and see the mac address in the arp cache. Edit: didnt notice the output, 10.100.0.204 via pptp2. Make sure the other end of that tunnel is up & pingable — LucentMoon, Aug 24 '14 at 14:22
Sorry for my poor description. Added configuration detail and current status. Vyatta can ping to every physical nodes. — Takuya Matsuyama, Aug 26 '14 at 0:55
Where does the Default Gateway of the Vagrant VM point to? Please also ping the 10.100.0.204 and 10.100.0.200 from the VM and check if you get an ARP resolution (arp -a). — Thieron, Aug 27 '14 at 12:29
Did any answer help you? if so, you should accept the answer so that the question doesn't keep popping up forever, looking for an answer. Alternatively, you could provide and accept your own answer. — Ron Maupin♦, Aug 10 '17 at 15:00
