Unable to connect to WAN when connecting from Client to OpenVPN server.

@ianh said in Unable to connect to WAN when connecting from Client to OpenVPN server.:

F) your NAT settings on pfS (hybrid???)
Based on another article I found I did have Automatic but changed this to manual and then copied and added NAT rules for the WAN to use the OPT1 interface, as explained here: pfsense-with-expressvpn-openvpn

ExpressVPN is a VPN provider. So that guide describes the setup to connect to a VPN provider and route the upstream traffic to it. That is not what you want.
In your case you do the part of the vpn provider for clients that connect to your server. So you have to route out their upstream traffic to the WAN gateway.

So you need an outbound NAT rule for the source range of the vpn tunnel network on the WAN interface.

If that does not work, again show your setup configuration. After you've obviously changed several things already:
OpenVPN server settings
interface settings
firewall rules
outbound NAT rules

@viragomann

Yes definitely made some changes but still cannot get the basic config to work.

Just to check what I am trying to do should be plausible right?

Use the OpenVPN to tunnel all traffic through it for management purposes?

Current set up is as follows I have managed to pull the information from the shell as I figure it might be easier than looking at screenshots.. if you want me to add screenshots I will:

So what is the concrete problem now?

Use the OpenVPN to tunnel all traffic through it for management purposes?

Not really clear, what you try to achieve. Once you write "route the whole client traffic over the vpn", then "for management purposes"(?).
Also in the config you have both settings, "push redirect gateway" and also "push special networks (IPs)". (?)

Current set up is as follows I have managed to pull the information from the shell as I figure it might be easier than looking at screenshots.

Since pfSense is configured via the web configurator, we are rather familiar with screenshots.

[ianh]

@viragomann

What I am trying to achieve is to use the VPN client on a Windows laptop (OS windows 10) to connect to the OpenVPN server which is running on a pfsense firewall version 2.4.5.

Once connected to the OpenVPN server I want the client to redirect all connections to the WAN through the OpenVPN server.

So far the Client can connect is given an IP from the OpenVPN server but is unable to connect to the internet.

There are two things I find odd when I connect with the client I am not given a default gateway in the IPconfig on the client for the VPNtunnel - possibly this is expected behaviour or not?

And no traffic is routed back through the Tunnel

Configuration from the GUI is as follows:

OpenVPN config

I think that should show the way it is configured... I am no doubt sure that there is something wrong with the config - yet this has never worked.

There has never been any issues connecting with the clients to the OpenVPN server.

It is how the traffic is routed, or the lack of routing once the client is attached to the Tunnel. The rules I pushed was to try to give the client a helping hand...possibly not a good choice...

If you can see any potential misconfiguration which is causing the traffic not to route properly would be appreciated.

Many Tnx.

Yes, that is as expected. OpenVPN does not set a real default gateway, instead it adds two routes for 0.0.0.0/1 and 128.0.0.0/1, which also covers the whole IPv4 range.

Your firewall rule on OPT1 only allows TCP traffic. You will also need UDP for DNS resolution.
You did not show the OpenVPN rule tab. So subject to that the rule on OPT1 should be the only real showstopper as far as I can see.

However, there are some additional miss-configurations in your setup:

The outbound NAT rules on OPT1 are useless, since you don't need connections to go out this interface. You only have incoming connections there.

Furthermore, also OPT1 by itself is not needed in your setup, but should not be a drawback if you have it.
Consider, if you remove it, to move the firewall rules to OpenVPN tab.

The port forwarding on OpenVPN seems useless for me and won't work anyway. No idea what you want to achieve with that.

The gateway option in the rule on OPT1 is also not necessary, since WAN GW is presumably the default gateway anyway.

OpenVPN server:
The domain name you provided as default domain is really your local domain?

As already mentioned, the push route options you entered in the advanced options are unnecessary, since the server pushes already the default route. Possibly that's an obstruction actually.

[ianh]

@viragomann

Tnx for the suggestions I have removed all the unnecessary NAT rules for OPT1 and as suggested even removed this interface.

I have removed the routes I was pushing in the advanced config on OpenVPN

And here are the rules on the OpenVPN tab also changed to allow both UDP and TCP

As far as I can see it is wide open so I don't understand why this would not be allowing traffic.

To me it looks wide open and we will have to close things down - but first we need the basics to work....

OpenVPN server:
The domain name you provided as default domain is really your local domain?

We have no local domain no servers on the LAN behind the pfsense we want to use this purely for the OpenVPN tunnel - so the LAN interface is pretty much redundant to us....

[viragomann]

@ianh
Is the outbound NAT rule for the OpenVPN tunnel network still in place?

Does the client connect without issues? Something in the log on client or server?

Show the clients routing table.

Try to ping 8.8.8.8 from the client.

[ianh]

@viragomann

This is the outbound rule for OpenVPN tunnel

This is the log from the client the connection shows no errors and this is the routing table:

@ianh said in Unable to connect to WAN when connecting from Client to OpenVPN server.:

This is the outbound rule for OpenVPN tunnel

Dude, you need an outbound NAT rule for the source of the OpenVPN tunnel network on the WAN interface!
I mentioned that already. Also that the outbound NAT on the VPN interface is useless in your case!

Outbound NAT is to be set on interfaces where the traffic is going out!
The vpn clients traffic is coming in on the OpenVPN interface and is going out on WAN. For getting responses back to the WAN IP, the source address in the outgoing packets has to be translated into the interface address. That is the job of the outbound NAT.

[ianh]

@viragomann

I am sorry I misunderstood your previous comment, as this NAT rule seem to be vital for this working can you give me some guidance as to how this should be configured?

You mention the following:

For getting responses back to the WAN IP, the source address in the outgoing packets has to be translated into the interface address. That is the job of the outbound NAT.

With this in mind I have configuered the NAT rule as follows:

What should I put for the interface?

With this configuration still the traffic does not route and as far as I can tell the Routing table does not change on the client:

The NAT rule is okay now. Ensure that the Outbound NAT is working in hybrid or manual mode.

If you have no love anyway, you have to do some troubleshooting. You the packet capture tool on pfSense to sniff the traffic on the respective interfaces.

Select the WAN interface and ICMP protocol and enter 8.8.8.8 at host, then start the capture and try a ping on the client to 8.8.8.8. Stop it and check the result.
If there is nothing switch to the OpenVPN interface and try again.
Post the results, please.

I have taken the packet capture and do not see anything in particular in wireshark other than:

Tnx.

@ianh
What is this??
I was asking for the simple capture result with default options!

[ianh]

@viragomann it is the result with default options.

I tried to upload to the forum but it would not accept the .cap files.

So I opened in wireshark and copied the results here...

Not sure how else you want me to display this?

[NogBadTheBad]

@viragomann looks like its being run under virtualization, check the MAC address.

[viragomann]

@ianh said in Unable to connect to WAN when connecting from Client to OpenVPN server.:

Not sure how else you want me to display this?

Simply copy and paste the result here. Enclose it in a code frame for readability.

[ianh]

@viragomann Tnx for your help in trying to get this sorted. There was an additional layer to this problem which was as @NogBadTheBad stated the pfsense server is a VM.

Long story short once we had rolled out a new OPENvpn server and chosen Automated NAT rules the connection is working and as we wanted all traffic is being routed via the VPN tunnel :)
