OpenVPN server on the Keenetic 1810

Post by persona » Sun Apr 19, 2020 9:01 am

Hello, I configure the OpenVPN server on the Keenetic 1810 modem. This is my first experience. The goal is to connect from the phone to the server, and get the local network ip, to use the local network at home. We would like to ask you to check the correctness of settings. At this stage the configs are as follows

Server config

mode server
proto tcp-server
port 1194
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
server 192.168.0.0 255.255.255.0
keepalive 10 120
cipher AES-128-CBC
auth SHA1

persist-key

Server seems to be working but there are problems, and the client is a problem

Post by persona » Sun Apr 19, 2020 11:59 am

the client configuration is not added to openvpn connect (ios) until I remove it from the configuration

Code: Select all

tls-client
tls-auth 1
<tls-auth> 
***
</tls-auth>
why?

These items are wrong:

Server:

  • Code: Select all

    tls-auth 0
    This should be:

    Code: Select all

    key-direction 0
    and what you have now should cause openvpn to crash and burn, so you probably listed it incorrectly, please double check and let me know.

  • Code: Select all

    server 192.168.0.0 255.255.255.0
    This is almost certainly incorrect because that subnet will conflict with your home network. Use this instead:

    Code: Select all

    server 10.8.0.0 255.255.255.0
Client:

well, I'll deal with this, but what do you say about the first letter?
my home network has an ip of 10.1.1.1, so I am using vpn 192.168.0.1
and how to achieve that when connecting via vpn to get into the home network, and get a home ip?

You get a VPN IP not a home IP but the principle is the same.

thank you, the VPN has earned, the connection is there.
I can't figure out why the IP(176.16.....) of the tunnel is assigned, and not the IP (10.1.....) of the home network.
And there is no access to the home network.
tell me what's wrong with the configuration?

Code: Select all

mode server
proto udp
port 1194
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
server 172.16.1.0 255.255.255.0
keepalive 10 120
cipher AES-128-CBC
auth SHA1
comp-lzo
persist-tun
persist-key
verb 0
route 172.16.1.1 255.255.255.0
route 10.1.1.1 255.255.255.0
client-to-client
push "redirect-gateway def1"
push "route 172.16.1.0 255.255.255.0"
push "route 10.1.1.0 255.255.255.0"
tls-server
key-direction 0
I try to ping the network from a PC (ip 10.1.*****) on a smartphone (172.16.******) connected via a VPN to the network passes.
but there is no access to the device on the network from a smartphone

Because that is how it is supposed to work.

Re: OpenVPN server on the Keenetic 1810

Good morning, may I please ask someone to paste the server and client configurations on the KEENETIC router, adding comments in the place of the XXXX certificates? It would be a very helpful solution.
