But once the tunnel reaches the OpenVPN server, you can direct port 80

Once it gets to the OpenVPN server (where you would also have the proxy
server), isn't it decrypted?
Lots of companies have VPN tunnels and then route web traffic through a
proxy so it must be possible somehow.

I assume I would have to use an alternative port or use firewall

Squid is an HTTP proxy, so no.
You can't really proxy OpenVPN as it's end-to-end encrypted with SSL.
If you issued the certs from your CA it might be possible to MITM it
but that may be illegal in many jurisdictions.
Alex
of course you can.
it's a basic IPTABLES rules and since openvpn uses a tunX interface you
can intercept all traffic from the tunX interface to the proxy.
but you cant force the clients to use the vpn as gateway to the whole
word but only to the VPN connection.
