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

Config:

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
Heikki,
You can get this to work by making openvpn and stunnel separate:
On the client side:
[openvpn] client = yes accept = localhost:443 connect = remote:20433
On the server side client = no accept = 20443 connect = 443
The traffic will be doubly encrypted. It might be easier just to use openvpn for this connection.
