[stunnel-users] OpenVPN with stunnel

Fri Mar 22 23:23:51 CET 2019

Hi,

To bypass the office firewall to access home server, I'm trying to run openvpn over port 443 with stunnel.
I managed to get to this point:

Log on client side

2019.03.22 22:15:13 LOG5[38]: Connection closed: 352 byte(s) sent to TLS, 2067 byte(s) sent to socket
2019.03.22 22:15:19 LOG5[39]: Service [openvpn] accepted connection from 127.0.0.1:51265
2019.03.22 22:15:19 LOG5[39]: s_connect: connected x.x.x.x:443
2019.03.22 22:15:19 LOG5[39]: Service [openvpn] connected remote server from x.x.x.x:51266
2019.03.22 22:15:19 LOG5[39]: Connection closed: 352 byte(s) sent to TLS, 2067 byte(s) sent to socket

Log on server side:

Mar 22 22:21:54 ssh-server-heikki stunnel[2797]: LOG5[2797:140127128753920]: connect_blocking: connected 127.0.0.1:8443
Mar 22 22:21:54 ssh-server-heikki stunnel[2797]: LOG5[2797:140127128753920]: Service [openvpn] connected remote server from 127.0.0.1:49366

Config:

Client
[openvpn]
client = yes
accept = localhost:1337
connect = x.x.x.xg:443
cert = C:\Users\heikki_lavaste\Documents\stunnel\stunnel.pem
verifyChain = yes
verify = 2
CAfile = C:\Users\heikki_lavaste\Documents\stunnel\ca-cert.pem
checkHost = stunnel.heikki-lab.local
sslVersion = TLSv1

Server

chroot = /var/run/stunnel
sslVersion = TLSv1
pid = /stunnel.pid
setuid = nobody
setgid = nobody
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
cert = /etc/stunnel/stunnel.pem
[openvpn]
accept = 443
connect = localhost:8443
cert = /etc/stunnel/stunnel.pem

The issue is probably nothing to do with stunnel but if somebody can help me figure this out, that'd be appreciated.

Kind Regards
Heikki
