VPN Disconnect and Ping Issue

Technical Support for Routers

Hi team.

I am having disconnect issue from VPN provider, and I reconnect to other VPN provider manually.

But I would use back the previous VPN provider when it is available back.

However, when I am using Windows and try to Ping/Tracert, it shows below log:

Pinging **.com [23.106.123.*] with 32 bytes of data:
Reply from 192.168.88.1: Destination port unreachable.
Reply from 192.168.88.1: Destination port unreachable.
Reply from 192.168.88.1: Destination port unreachable.
Reply from 192.168.88.1: Destination port unreachable.

Ping statistics for 23.106.123.*:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Tracing route to **.com [23.106.123.*]
over a maximum of 30 hops:

  1     4 ms     3 ms     1 ms  console.gl-inet.com [192.168.88.1]
  2  console.gl-inet.com [192.168.88.1]  reports: Destination protocol unreachable.

Trace complete.

Wonder if it is normal behavior?

My expectation is it should return Destination Host Unreachable. However after restart router it returns Destination Host Unreachable.

Device: MT3000 using repeater mode
Firmware: 4.1.3

Sorry, I don’t understand your question, can you explain more?

Hi, if there is two OpenVPN profile, VPN A and VPN B.

VPN A is down and disconnected, I reconnect to VPN B meanwhile testing to ping via CMD in Windows to see if VPN A is up.

The result is showing Destination protocol unreachable, however expectation is Destination host unreachable.

As you can see, the tracert stop at router side which is 192.168.88.1 (my default router gateway). It should go out to the internet and trace somewhere else instead stopped at my router.

I think both of these results are enough to determine that VPN A is not working properly.
Destination host unreachable results depend on whether the destination address can be correctly routed. You can try refreshing the router’s route cache by using the following command

ip route flush cache

Noted, will try out next time on this, thank you.
