How to create an OpenVPN client to StrongVPN

[powerextreme]

I am working on this setup. I have gotten to step 10. So far I am able to get the OpenVPN client up and running. I have noticed at this point internet connectivity goes down. DNS still works but can't ping to IP's on the Internet.

I know I am only at step 10 but just curious as to what happened when I started the OpenVPN client service.

Anyone got any ideas?

Hi everyone.  Total NOOB here.

I've been trying to get a StrongVPN client set up on pfSense latest version (2.1.3).

I tried the initial tutorial by ericab, who started this thread, as well as the tutorial in the link by pkwong.  However, after a certain point, the screenshots start to differ slightly (in terms of the options) and I can't figure out what I'm doing wrong.  Also, on my machine, it seems to distinguish between IPv4 and IPv6 LANs.  Not sure if that is part of my problem.  That's above my head at this point.  I'm reeeaaaly clueless about this stuff, so your guys hand-holding is really appreciated.

I was able to load all the certificate information and get a positive indication of connection under system logs.  One other thing I noticed,  when I set up the certificate, I did not get an "in-use" indication within the GUI, like you see for the other one that was already there.  Could that be part of the problem?

If there is an updated tutorial, or if it's known that a StrongVPN Client will not work with the latest version of pfSense, I'd greatly appreciate the help.

Thanks!

What alternative(s) to StrongVPN have you folks found?  I was looking at privateinternetaccess but, like others, the tutorials I find online are for older versions, and as this will be my first time doing something like this, I'm going to need a lot of help.

AirVPN works beautifully.

Hello,
I can not get openvpn working with strongvpn… No Internet access.

I have squid installed also... I also have my lan ip range set as 10.10.10.1 with the DHCP range of 10.10.10.5-254

I need a config and im willing to pay for it via paypal if need be. $20 USD

I need the following ports forwarded 53-80-25-443-110-2525 to 25 - 587 all tcp/udp

Here is the version of pfsense I am running - pfSense-memstick-2.1.3-RELEASE-amd64-20140501-1552

Thanks in advance for any help.

Perhaps as a newbie to pfSense myself I have miss-understood something concerning the outbound NAT manual / rules.

I have configured as per the guide with only 1 exception. The encryption algorithm i had to employ was: AES-128-CBC (128bit) Going with this algorithm not only allowed my openvpn to establish but also become viable to send / receive data over.

My problem is just like everyone else who has posted on this topic. ALL traffic is routed through the vpn across all the networks attached. (currently 7 different subnets NAT'ing)

So if I have read correctly, it sounds like the magic I need to employ happens at the NAT-Outbound-Manual Mappings. If so how do I specify these mappings? When I select manual mappings a number of rules are automaticly generated for all the attached subnets as well as 1 for 127.0.0.0. How and where do I specify to allow only select IP's or policy based exceptions to utilize the VPN while still allowing all regular NAT connections to traverse my regular WAN connection?

Finally, I see that this has been asked in the past but further clarification would be great. Why in the routing section is there the ability to specify a default gateway (typically for the regular WAN) if this does not work? Is this a possible bug?

My installation is:

2.1.4-RELEASE (i386)
built on Fri Jun 20 12:59:29 EDT 2014
FreeBSD 8.3-RELEASE-p16

And it is installed on a watchguard firebox 1250e. Not the nano but full install headless on a hard drive.
Thanks in advance for your help!

I have since doubled up all my manual outbound nat rules to allow NAT to the VPN interface. Then went back to the LAN firewall rule and pointed gateway at my WAN interface. At first the results were good, I was getting my local WAN ip showing up in whatsmyip.com, however after a few minutes and refreshing the page a few times, I see that I am again being directed out the VPN interface….  I am seriously stumped and baffled by this behaviour.....

When my only LAN rules looks like:
IPv4 * * * * * WAN_DHCP none

I traceroute and see:

Hop 1 is my local ISP modem/router
Hop 2 I suspect is my ISP internal network
Hop 3 is my ISP's external addy....
etc...

Clearly going through my WAN....

And if i modify my only LAN rule to look like:
IPv4 * * * * * STRONGVPN_VPNV4 none

traceroute whatismyip.com

What gives????

edit:
I should also mention that I am using squid. Dunno if that makes a difference or not. I just thought it might have bearing as my trace route packets seem to be routed properly but not the web requests....

[toyotahead]

ok… a bit closer possibly....

I have uninstalled squid2, and squidguard2.

From a LAN client ip, i can traceroute google.ca and hit my regular WAN gateway. As well http requests are being NAT'd throu regular WAN gateway. This is expected and correct.

However if i ssh into pfsense and traceroute google.ca, it still goes out via the vpn gateway....

Thoughts?

[toyotahead]

Maybe a bit more clarification as to what I am trying to achieve…

I am trying to get the pfsense box as well as all traffic generated on the lan subnets to still NAT to the shaw gateway. Only select ip's or layer7 detected protocols etc to be NAT'd out the VPN.

I believe that has to do with getting the pfsense box itself to use the default shaw gateway rather than the vpn gateway. Oddly enough in the routing section of pfsense when you specify multiple gateways, there is a box labelled default gateway. I have this set to the shaw gateway. Unfortunately this directive doesn’t seem to be adhered to....?

[toyotahead]

Just a thought… Why is there a 0.0.0.0/1 to 10.8.1.61 ahead of the default gateway line?

This is with the openvpn activated:

My gut is telling me this is the error I have been trying to track down. If this is so then how am i going to be able to amend this seemingly automaticly generated routing table? I have my NAT Outbound NAT rules set to manual at present.

Is there a way to make it so that when the vpn establishes that this route is not done?

[toyotahead]

SOLVED

Ok in the advanced config section of the openvpn client just DONT add the "redirect-gateway def1;" This effectively will override the route table with a blanket forward all traffic out the vpn tunnel.

NOW you are able to specify in your firewall rules which filtered matches you want to go out the VPN tunnel via the advanced features - gateway - and select the gateway of the vpn.

CHEERS EVERYONE. I see this has been a brutally long thread and many times this very question on how to selectively push traffic though the tunnel has been asked with no definitive solution. I am glad to have been able to contribute. :)

The server by default will send this to the client…
Anyway, to prevent all traffic being routed through a vpn connection by default, you just need to add "route-nopull;" to the advanced section, then do your individual routing on your firewall rules.

I have had some problems setting up AirVPN on a new pfSense box, as posted elsewhere

I stumbled on this post, and despite following the instructions in detail, I simply cannot get a reliable internet connection. At the end of the guide I am able to confirm that I am using the AirVPN IP address instead of my own, but get a very slow internet connection, with most pages timing out.

I have tried a number of different servers, all using the UDP straight proticol, but all have the effect.

Following another guide I am using remote-cert-tls server;verb 3;explicit-exit-notify 5;key-direction 1;auth SHA1;keysize 256;key-method 2;tls-cipher TLS-DHE-RSA-WITH-AES-256-CBC-SHA;persist-tun; persist-key in the advanced configuration of the OpenVPN client. I have tried omitting the persist-key option as suggested but this makes on efferct

This is a typical OpenVPN log:-

A connection is alway made with AirVPN and their gateway is always green after a number of seconds, see attachments

I can not us the monitor IP address as stated in the guide, bit have used 10.4.0.1 (which is an AirVPN address given in another setup guide) or google's 8.8.8.8

The OpenVPN connection is clearly been made and a gateway to AirVPN is being set up, I am at a complete loss as to why I can't get an internet connection.

I did wonder whether to try different ports rather than 443 UDP straight, but thought that I would post here first

I would be very grateful of some assistance, I have hit a brick wall and just don't kno where to turn next

I am running Snort, Squid and ClamAV as well, if this makes any difference

Also I am currently using the same subnet for WAN and LAN, could this be the cause of my problem?


[sysfu]

What happens when you connect to the AirVPN account using an OpenVPN client on your computer? Do the problems go away?

[clevoir]

Yes when I use AirVPN's own client software I get no problems at all using the same servers and UDP 443 port that I have tried to set up my pF=fSense box with

As such I can't see it is a problem at their end, more the pfSense setup?

At the time of this problem I was using the same subnet for WAN and LAN, and wonder if it might be part of the problem?

I now have WAN and LAN on seperate subnets now, and will try again

[sysfu]

Yes, typically the IP address assigned to each interface must be on a different network or subnet. That's how the router is able to determine which interface the packet should be forwarded to. If both interfaces are on the same network, it doesn't know how to decide between the two.

Think if you were tasked with delivering a package to an office to a person there named "Charlie". When you get to the office, you find out where are two people named "Charlie".

How would you be able to decide definitively on which desk the package should ultimately go? You wouldn't without more info.

[clevoir]

I have just found that AirVPN block all conections on UDP ports where a proxy is used. as I am using Snort, Squid and Clam AV I guess that this will be why I can't get a connection as I was uisng UDP port 443

I am to try agian using TCP ports but appreciate that the connection speed might be slower

[clevoir]

This morning I tried again using AirVPn TCP 443 and 80 settings and still can't get an internet connection.

Im not sure its related but a couple of things worth checking.

Check WAN interface is set to Active but type = none and LAN is set yo your subnet of choice.
Do not set your WAN address to a private range, i.e 192.168.x.x.
Also I noticed your routing screenshot doesn't show a default route, this should be WAN_DHCP.
Ive attached a shot of my NAT rules too, hopefully these don't add to your confusion as I have a lot more interfaces as well as some VPN_LAN -> non VPN output rules but you'll get the idea if you take the time to read it.
AirVPN works fine with UDP and proxies like squid etc so suspect you have a weird config somewhere back up the chain, moving to TCP isn't going to help I suspect.

Take your time, go through the AirVPN guide step by step and verify at each stage you are seeing the expected behaviors, i.e can you Ping / DNS lookup at the interim stages.
