    Default Nonstandard VPN client port

    Trying to connect to a VPN over port 443, but traffic is not exiting the WAN interface. I can see it leaving the client, going into the LAN interface, but never exits the WAN.

    I added the following rule hoping it would allow the traffic, but it does not. I also moved it right above the last deny line. Is there another location that UDP traffic over port 443 may be blocked?

    You will need to also move the GUI from the default port of 443. I'm assuming you have moved the OpenVPN port already.

    Even for a client behind the firewall?

    Btw, I fixed this by adding a by-pass rule. Removed the advanced access rules and with the by-pass rule traffic flowed as expected. I put in a rule specific to the external VPN IP & protocol.

    Sorry one last response before I move on. I think I understand your question and I may not have been totally clear in my original post. A client behind the firewall was attempting to connect to a remote vpn server. The untangled server in question was neither the vpn client or server.

    The traffic was getting held up somewhere in untangled. I have Application Control, Web Filter, Bandwidth Control, Firewall, Ad Blocker, Reports, Intrusion Detection installed. I couldn't see the blocks happening. But as I type this I only checked App Control, Web Filter and Firewall.

    Then nothing is needed for out going sessions. WebFilter is probably affecting your outgoing VPN so I would bypass WebFilter using a policy rule.
