No port 80, 443 access via openVPN

  • I have a working openVPN setup on pfsense 2.1.5 and clients can connect without any problems. The problem arises if I try to access any internal or external web service. Any connections on port 80 or 443 fail. If I attempt to access a web service on a non-standard port (8443) it works. I can access internal servers via ssh, rdp, anything I've tried other than a web interface. Initially I thought maybe I was missing some browser configuration or something like that on the client but the same thing happens if I telnet to port 80. The same thing happens if I try to connect to public web servers(ie. google) when connected.

    Has anyone seen anything like this before? I'm open to any suggestions.

    And what are the rules on your openvpn tab in the firewall?  Are you using squid in pfsense as proxy?  Do you have any port forwards setup with those ports?

  • The only rule I have is the auto generated one, Allow all from all.

    I am not using squid as a proxy. However you asking the question made me start thinking in a different direction. I have a content filter in between pfsense and my network. I bet something is happening there. That would explain why it's just http/https.

    Thanks. If I figure it out I'll update.
