Windows 10: IP route not working for VPN connection

I am on Windows 10 Home Version 1903

I have installed SonicWall VPN as a workaround and Cisco VPN client. My VPN client shows "connected" a few secs after I start the vpn session

VPN Client creates the following IP Interface on my Windows

Ethernet adapter Ethernet 3: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::745b:83cd:3481:761f%12 IPv4 Address. . . . . . . . . . . : 172.77.0.114 Subnet Mask . . . . . . . . . . . : 255.255.255.248 Default Gateway . . . . . . . . . :

And also Configures the following IP Routing rules

IPv4 Route Table===========================================================================Active Routes:Network Destination Netmask Gateway Interface Metric 172.16.0.0 255.255.0.0 172.77.0.113 172.77.0.114 100 172.77.0.112 255.255.255.248 On-link 172.77.0.114 291 172.77.0.114 255.255.255.255 On-link 172.77.0.114 291 172.77.0.119 255.255.255.255 On-link 172.77.0.114 291

I am supposed to connect to remote server IP address

172.16.14.65

when I execute the following PowerShell command line

Find-NetRoute -RemoteIPAddress "172.16.14.65" Select-Object ifIndex,DestinationPrefix,IPAddress,InterfaceAlias,NextHop,RouteMetric -Last 1

I get this result

ifIndex : 12DestinationPrefix : 172.16.0.0/16IPAddress :InterfaceAlias : Ethernet 3NextHop : 172.77.0.113RouteMetric : 65

So, what I get from this is that the route should work as expected.

I am running wireshark on Ethernet 3 interface and I am checking on traffic on this interface.

When I try to ping 172.16.14.65, I do not see any traffic going through this interface in Wireshark as a matter of fact, when i sniff traffic on all interfaces, i dont see any icmp traffic at all

Can anyone show me some pointers as to what could be wrong here ?

best regards, Martin

VPN routing table issues on 1809

I have a program using DotRas to set up a VPN connection. My program will set the VPN interface not as the default gateway and insert custom routing rules so that other programs won't pass through the VPN connection.

Code:

// works before 1809 updateRasEntry entry = RasEntry.CreateVpnEntry(EntryName, VPN_Name, strategy, device);

entry.Options.RemoteDefaultGateway = false;

entry.Options.IPv6RemoteDefaultGateway = false;
I'm 100% sure it works before the1809 update.

After install 1809 update, I got two new routing rules:

Before connecting VPN connection:

Code:

Route     Mask    Gateway     Interface      Metrics0.0.0.0    0.0.0.0    192.168.1.1(my router ip)    192.168.1.2(my ip)   
[b]36[/b](other)
After connecting:

Code:

Route     Mask    Gateway     Interface      Metrics0.0.0.0    0.0.0.0    192.168.1.1(my router ip)    192.168.1.2(my ip)   
[b]4276[/b]0.0.0.0    0.0.0.0    On-Link    10.0.0.68(my vpn interface ip)   
[b]26[/b]10.0.0.68  0.0.0.0    On-Link    10.0.0.68(my vpn interface ip)    [b]281[/b](other)
I figured that after connecting it is inserted with two loopback routing rules and all traffic will go through the vpn interface.

Googled found no solution but some other discussions:

Network Routing Tables


Hi everyone!


I recently started using a VPN. However some websites block VPN ips so I can't visit them.
To solve this problem I would like to add the blocked website's IP to my route table.
It works fine on my other laptops but on my PC it doesn't seem to function. I ran the following command as an administrator in my cmd. Got the OK! feedback message but I still get blocked from visiting the website when on a VPN.


Code:

Code:

Route add [website IP] [Default Gateway]

At the bottom of this screenshot :






you can see that the IP is indeed added to the list but sadly it doesn't function. I have been suggested to reinstall my Windows 10 but was wondering if there aren't any other solutions to this problem.


Thanks in advance!

 

Vpn ( trusted Vpn)

Hi everyone.
I am not an expert about Vpn and that's why I would like to know if someone could list me a few trusted Vpns, I would really appreciate any suggestion/ advice.

Thanks.
