If this is VPN, then they need the PPTP or L2TP protocol. If this Open VPN
uses something "odd-ball" then the Open VPN isn't very "Open".
The Access Rule needs to allow PPTP (or L2TP) outbound and must be anonymous
(All Users).
They have to disable the Firewall Client while using it.

Do the VPN thing
When done with the VPN thing right click on the FWC icon by the

Hi all. I would appreciate any help on the following issue:
I have a client that needs to connect from an internal machine to a
client's server that uses OpenVPN. We have ISA 2004 installed w/ SBS,
and the firewall seems to be blocking the outgoing OpenVPN connection.
I have already opened up port UDP 1194 outbound.
Can anyone successfully openvpn out of internal network?
Thank you.
Thanks for the response Philip!
This is taken directly from their site: http://openvpn.net/
OpenVPN implements OSI layer 2 or 3 secure network extension using the
industry standard SSL/TLS protocol, supports flexible client
authentication methods based on certificates, smart cards, and/or 2-
factor authentication, and allows user or group-specific access
control policies using firewall rules applied to the VPN virtual
interface. OpenVPN is not a web application proxy and does not operate
through a web browser.
Does OpenVPN support IPSec or PPTP?
There are three major families of VPN implementations in wide usage
today: SSL, IPSec, and PPTP. OpenVPN is an SSL VPN and as such is not
compatible with IPSec, L2TP, or PPTP.
I actually did try opening port 1194 for SSL (using the ISAtpre tool)
but it still did not work. Do you have any other ideas?
