I have a laptop that is connected wirelessly to 192.168.1.0/24 network using DHCP and wired to 10.10.10.0/24 network static settings with NO DEFAULT GATEWAY set up.

The goal was to access to external addresses using the default gateway on the wireless network (192.168.1.1) and the internal network (10.10.10.0/24, 10.10.20.0/24 and so on... 10.10.60.0/24) using the wired NIC. So I've added the following persistent routes:

===========================================================================
Persistent Routes:

  Network Address          Netmask  Gateway Address  Metric

       10.10.60.0    255.255.255.0       10.10.10.1       1
       10.10.50.0    255.255.255.0       10.10.10.1       1
       10.10.40.0    255.255.255.0       10.10.10.1       1
       10.10.20.0    255.255.255.0       10.10.10.1       1
       10.10.30.0    255.255.255.0       10.10.10.1      11
       10.10.10.0    255.255.255.0       10.10.10.1       1

===========================================================================

The routing table is the following:

But, after all this the packets take the wrong way:

C:\WINDOWS\system32>tracert -d 10.10.60.1

Tracing route to 10.10.60.1 over a maximum of 30 hops

  1     5 ms     3 ms     3 ms  192.168.1.1
==============================================
^C

C:\WINDOWS\system32>

Why do the packets take the 192.168.1.1 way ?

Shouldn't packets go the persistent route (10.10.10.1 )?

    Remove the extra routes to 10.10.10.0. You are already on that network directly, no need to try to reach it via a gateway. It most probably messes the routing table up.

  • Thank you for the answer but even without that line the behaviour is the same: C:\WINDOWS\system32>route print 10.10.60.0 IPv4 Route Table Active Routes: None Persistent Routes: Network Address Netmask Gateway Address Metric 10.10.60.0 255.255.255.0 10.10.10.1 1 C:\WINDOWS\system32>tracert -d 10.10.60.1 Tracing route to 10.10.60.1 over a maximum of 30 hops 1 5 ms 3 ms 2 ms 192.168.1.1

  • You're testing with 10.10.60.x but I don't see that in the active routes list? I would remove the static route for 10.10.10.x, restart and try to get to the point where all the persistent routes are showing as active. Then test again

Did you restart networking or enable/disable the adapters? You might need to restart the TCP stack to get the new routing stuff recognized. Just a thought.

  • Disabling and enabling both adapters did the trick! Thank you very much sir!

What I usually do is followings 

route add 10.0.0.0 mask 255.0.0.0 10.28.15.201 -p

in addition to above you should always add interface number like (if you are not planing to swap the interfaces later on)

route add 10.0.0.0 mask 255.0.0.0 10.28.15.201 -p IF 12

(interface list is shown in route print)

I just added gateway for both interfaces, windows gave me warning that there is gateway conflict, i just Said OK, and then added routs on specific interface and it works for me .

here is what i have achieved with above mentioned route add
