Gl-ar750s slate and expressvpn not working

jstiago · 2020-04-20T10:17:49.216Z

config from expressvpn is not working. Trying to dig in I think the error is:
Mon Apr 20 09:51:48 2020 daemon.notice openvpn[3793]: UDP link local: (not bound)
Mon Apr 20 09:51:48 2020 daemon.notice openvpn[3793]: UDP link remote: [AF_INET]193.37.32.31:1195
Mon Apr 20 09:52:24 2020 daemon.err odhcp6c[11722]: Failed to send DHCPV6 message to ff02::1:2 (Permission denied)
Mon Apr 20 09:52:48 2020 daemon.err openvpn[3793]: TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Mon Apr 20 09:52:48 2020 daemon.err openvpn[3793]: TLS Error: TLS handshake failed

just using openVPN, I think everything else is off.
have tried with firmware 3.100, 3.101, 3.104

trying to also reach out to expressvpn

jstiago:

AF_INET

it looks like your config is trying and failing to connect over ipv6 and then there is a TLS connection error with express vpn.

I don’t think that changing firmwares will change anything, you are probably wasting your time there.

Can you try different .ovpn configurations from expression to see instead?

to add, I’m able to use the same configs on tunnelbrick on a mac without issues.

sorry I’m still a bit of a noob on this. I’m not sure how to do that.

the ovpn file is something like this

dev tun
fast-io
persist-key
persist-tun
nobind
remote australia-sydney-ca-version-2.expressnetw.com 1195

remote-random
pull
comp-lzo no
tls-client
verify-x509-name Server name-prefix
ns-cert-type server
key-direction 1
route-method exe
route-delay 2
tun-mtu 1500
fragment 1300
mssfix 1200
verb 3
cipher AES-256-CBC
keysize 256
auth SHA512
sndbuf 524288
rcvbuf 524288
auth-user-pass

...

go to express VPN and download a different open VPN config - it should come as a .ovpn file.

I’m not familiar with this vpn service, but mine offers different configuration files for specific servers or particular countries.

I would try a configuration from expression VPN that singles out a particular server. Your new config should then have an IP address isntead of:

remote australia-sydney-ca-version-2.expressnetw.com 1195

I found the issue. It looks likes the main router’s firewall was blocking ports from certain IP ranges. all good now. thanks man
