--tls_crypt does not work in Dubai

Post by pooja.jain9203 » Mon Apr 30, 2018 12:12 pm

Hi,

I'm using openvpn 2.4 with --tls_crypt. OpenVPN client gets connected successfully but unfortunately user is not able to access any website.

Following is client config :

client
dev tun
proto tcp
remote <server_ip> 443
resolv-retry infinite
nobind
user nobody
group nogroup
persist-key
persist-tun
remote-cert-tls server
cipher AES-256-CBC
verb 3
auth SHA512

<ca>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
</key>
<tls-crypt>
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
</tls-crypt>

------------------------------------------------------------------------------------------------------
Server configuration below :

port 443
proto tcp
dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
;push "route 192.168.10.0 255.255.255.0"
;push "route 192.168.20.0 255.255.255.0"
push "redirect-gateway def1"
;push "dhcp-option DNS 208.67.222.222"
;push "dhcp-option DNS 208.67.220.220"
keepalive 10 120
tls-crypt ta.key
auth SHA512
cipher AES-256-CBC
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
log-append /var/log/openvpn.log
verb 4


Any help in how to debug?

--tls-crypt clearly works properly, even in Dubai ..

Can you please share your configuration details? Also which openvpn client are you using?

I asked you to share your log; The tiny snippet you chose to share clearly shows you have a connection.

Therefore, --tls-crypt is working properly .. I presume you are in Dubai ..

Problems getting out to the Internet are often caused by network set-up and firewalls rather than OpenVPN itself.
