Hello all,
I have Pound set up to listen on a single IP address for HTTPS connections
and then based on the Service's HeadRequire section I redirect the
connection to a port on localhost, then I have Stunnel re-encrypt it and
send it to the appropriate backend server (either a WebDAV server or an
OpenVPN server).
The WebDAV works like a champ and the OpenVPN AS lets me logon to their user
page and download the pre-configured client, but I think the OpenVPN client
communications are getting dumped because it is not HTTP RFC compliant.
1) Is there any way to tell Pound to NOT sanitize inbound communications
(preferably at the Service level)? I would like to tell pound to pass
anything with a hostheader containing "vpn" back to my OpenVPN box.
2) How can I confirm that Pound is doing what I'm guessing above? (I've
turned the logging up to 5 and don't see it denying connections or otherwise
complaining in /var/log/daemon like I would expect)
.... and yes I know I can run OpenVPN on a different port and not need to do
most of this, but I want it running over tcp 443 for my own selfish reasons
:)
My setup is as such
(Pound/Stunnel) - OpenBSD 4.6 - PoundProxy 2.4.4, Stunnel 4.2.7
(Webdav) - OpenBSD 4.6, default chrooted Apache 1.3 installation
(OpenVPN) - Ubuntu 9.10 desktop, OpenVPN Access Server 1.3.5
