New OpenVPN setup for road-warriors - connected but no routing

kejianshi

Yes - You have to export your client config again and reinstall it on windows.
So, uninstal the old one then reinstall the new one.
Also make sure your firewall rules in pfsense on the openvpn tab pass to anywhere, just like your LAN rule.

(I'm all IPV4 here, so if this is a IPV6 glitch, all bets are off)

Cylindric

No idea what I'm missing now. I have some images of my current setup.

I'll try a full removal of the client from the PC and clean up whatever I can see, and try again. As it's connecting but not routing, it smells like the problem of not installing as admin, even though I definitely did.

I assume that if the correct routes are created and visible in "route print", then admin isn't the problem?

Still using the TAP adapter? Seriously want you to reconsider using TUN for you own sanity.
Openvpn Should come with a warning that says "Don't use TAP unless you absolutely intend to bridge to your server network or absolutely require layer2".
As a mater of fact, Some openvpn tools do say something like that. To get TAP to work, you will need IPs assigned, so DHCP start and end range. Probably want bridging. Probably want LZO compression on no matter what you use. Probably want type-of-service checked…

But, unless you can tell me why you need TAP, probably need to dump it and use TUN for this.

Cylindric

Ah, sorry my bad - I had tried both, so think I must've changed it back before screenies. I'll set it to TUN now and test again just to be sure! I also found the "Management Interface" option for the client download, and the newer version of OpenVPN, so I'll get through those…

kejianshi

Something just occured to me. What versions of openvpn client export package are you on? If you go to your packages, is there an update available for it? Its a one button push to update that. Basically you just press the little pkg button out to the right. Before you export a new TUN adapter (You have to export a new config each time you make a server change to be safe), please make sure client export package is latest one.

Cylindric

Doesn't appear to be, I only installed it a few days ago too - I'm on 1.0.11

kejianshi

If its not offering an update there, you version is current. We are on the same thing.

kejianshi

Sorry to nit-pick but just checking. When you stipulate your tunnel IP make sure that subnet isn't used on the client side or the server side. Give the openvpn tunnel a seperate range.

So if client is on a 192.168.1.0/24 and server is on a 178.x.x.x make the tunnlel network something like 10.122.20.0/24 (or whatever)

No need to push routes or any other madness.

I do provide DNS servers and NTP servers though. Get two online for NTP servers in your timezone and use 8.8.8.8 and 8.8.4.4 if you want google DNS

I also provide a default domain NAME. Just pick a name like tunnel1194 if you only use one server.

Cylindric

Still no joy, even with both server and client set to "TUN". With or without the Management part. With 2.2 or 2.3-x86.

All firewalls off on the windows box?

I don't understand what are you trying to do there.


   Description . . . . . . . . . . . : TAP-Windows Adapter V9 #2
   IPv4 Address. . . . . . . . . . . : 172.29.0.6(Preferred) 
   Subnet Mask . . . . . . . . . . . : 255.255.255.252

This for sure again looks like /30.

Nitpick away - whatever it takes :)

My remote test PC is on a 172.29.14.0 subnet with a mask 255.255.255.0, at the moment the IP is 172.29.14.100

My pfSense LAN subnet is 10.10.0.0 with mask 255.255.255.0, and the IP is 10.10.0.3

The server "Tunnel Network" is 172.29.0.0/24
The sever "Local Network" is 10.10.0.0/24

The client "Tunnel Network" is 172.29.0.0/24
The client "Local Network" is 10.10.0.0/24

The firewall is now disabled on the PC. Not sure what the Virgin SuperHub might be doing though - although as the tunnel is established and I can see that in the pfSense status, I assume any intermediary firewalls just see "traffic", not anything specific.

This for sure again looks like /30

I can only assume this is coming from the config in pfSense, I'm not setting that mask anywhere. I have /24 in all configs.

Please, tick the proper checkbox so that this net30 topology is NOT used.

What screen are you seeing that on? I just get the attached.

As already posted elsewhere. This ONLY is available if you set up the interface as TUN. Not with TAP.

I am on TUN now.

Well, then it's not available in 2.0.3. Time to upgrade. :P

Cylindric

2.0.3 is the latest I could find. You folks running the 2.1 RC?

kejianshi

You can go to 2.1RC

http://snapshots.pfsense.org/

But honestly, this should work fine on 2.03. It should be a 5 minute setup from start to finish.

Some basic little thing is broken and its possible its not even anything to do with pfsense.

I'll read you config again.

Cylindric

Thanks. Tomorrow I'll probably delete all the settings and start from scratch - I made some wrong turns at the start that may be lingering.
