Can't connect to VPN

[Montrey]

Hey,is there someone, who is an expert in routing
questions?

I have 3 networks connections, and my VPN using one of them. But I can connect VPN ONLY if main network is connected. If I turn on second or therd,VPN can't connect.
I think this problem is because of routing.

IP intervals :
main - 10.34.16.*** mask 255.255.255.0 (255.255.255.255 for VPN)
second - 10.236.111.*** mask 255.255.255.0
therd - 10.100.20.*** mask 255.255.255.0

They all using an automate сonfiguration.
Help me :shock:

Are you using a gateway in all connections? If so, remove the gateway entries and leave a gateway only in one connection.

Also, make sure all 4 (VPN, and the three connections) are set as Home Network and try again...

 

[Montrey]

Hm... Try this now.

 

[Montrey]

Hm. How could I remove the gateway, if all of them use automatic configuration?

 

[limneos]

Well...find out what IPs they're getting automatically from the DHCP server, and use them manually, leaving the gateway blank.

To see what IP each adapter gets automatically, run CMD and type IPCONFIG

 

[Montrey]

I can't do that, all of the servers a configure so that they don't give an access to network if I get an IP manually.

Ok, although I can't replicate the problem, (I have 2 network adapters and when I create a VPN it works fine) I can only suggest that you delete the VPN, enable all three connections and create the VPN again, lest it defaults to your prefered connection.

Or if applicable, change all your subnet masks to 255.0.0.0, but you said you can't manually edit that...

 

[Montrey]

Yep, I can't change mask =\

 

[Montrey]

Ok, I done it. Just add a route to my VPN server through main network gateway with 255.0.0.0 mask.

Glad it worked out for you
