OpenVPN Server Gateway Redirect
-
@viragomann
UDPVPNSERVER is the interface I created for The VPN Server, -
But PUREVPNCA may be a VPN service you're connecting to.
-
If you disable the rule on the OpenVPN interface you have to add a rule to the UDPVPNSERVER to allow access to your DNS server. The existing rule only allow access to the WAN gateway.
-
@viragomann What Should go in Source and Destination, for dns
-
The source should be the access server tunnel network.
The destination is the DNS servers you provide to the clients. Taking a look at your server settings, these are 192.168.40.4 and 192.168.40.1. -
@viragomann Still not working , DNS_Server is alias for DNS ip address,
-
For troubleshooting only provide public DNS servers on the OpenVPN server settings. The firewall rule you've set on UDPVPNSERVER actually allows access to any, so that should work.
If it doesn't determine if it's an DNS issue by accessing an Internet site by its IP. -
@viragomann Even by ip I cannot access....
-
Everything looks correctly.
To investigate use the Packet Capture feature from the pfSense Diagnostic menu.
Start a capture on the UDPVPNSERVER interface while you try to connect to a public site on the vpn client device and check what you get.
Take an additional capture from WAN, in the IP box put the destination IP you try to access for filtering. Here you should see the packets as well, but with your WAN address as source. -

@manjotsc said in OpenVPN Server Gateway Redirect:
@viragomann FROM UDPVPNERVER
And what does it look like on WAN?
Which destination are you trying to access?
-
@viragomann I don't know what was causing it, but I noticed that each time I would associate an interface with vpn server. It would cause that problem where vpn connects but no Internet, so all I had to is restart the OpenVPN server and create a rule under the interface, once the interface was created, and it been working for couple days.
