How to create an OpenVPN client to StrongVPN

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?

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....?

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?

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?

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.

I got it working now, I was missing an Outgoing NAT rule for the VPN gateway

Thanks for you help

Hi all, I've read this entire thread and I think I have a handle on it, but I always get this in the logs:

May 14 12:30:18 openvpn[96614]: Local Options hash (VER=V4): '6088b372'
May 14 12:30:18 openvpn[96614]: Expected Remote Options hash (VER=V4): '0b6efc44'

May 14 12:30:18 openvpn[96614]: UDPv4 link remote: [AF_INET]173.195.6.142:4672

192.168.3.3 is the IP of my WAN because I have to be behind their stupid LTE router.

I have no problems with accessing the internet from clients and I've followed the instructions to the letter. I'm using 2.2 RELEASE of pfsense.

Any ideas why it's just hanging there? It never connects.

Thanks!

Please can you help me how to make VPN between two sites?

guybrush2k4

Hi guys,
Lately I had some time to think. and finally I bought a pc-based firewall (Attom d525 and 6 gigabit inter ports)
so I'm back with the idea of a serious router firewall using pfsense.

but no sure if this would be posible.

1 I can't remove my provider router (because I was not able to replace it with pfsense due to the TV packages)
so I have my router forwarding everything to the pfsesnse box and that normally works.
2 the question is now i'm thinking on getting an vpn to access streaming services from abroad. (using openvpn)
do you think it would be posible with to have the pfsense box with the vpn open 24x7 and to have all the pc on the same network but only for certain ips modify the output to internet to use the vpn the rest of the ips going throught the standard gateway? (no vpn)
so they have access to my servers in the local network but internet they have different accesses.

At the moment I'm just thinking but That can be a nice setup.

Regards.

OpenVPN is the most secure VPN protocol use for highly encrypted data transfer but it slightly impacts on the internet speed because of encryption but it always hide your data successfully.

Here is an official guide about how to setup OpenVPN https://openvpn.net/index.php/access-server/docs/admin-guides-sp-859543150/howto-connect-client-configuration.html

I'm having some trouble with setting up StrongVPN on pfSense. The tunnel is connects successfully and the gateway is up, but I can not get traffic to go through it. My intent is to only have traffic from a single interface routed through it with policy based routing. I have two other OpenVPN site-to-site tunnels up and working with policy based routing on the router, so I have been able to successfully do something similar before. I just can't get this to work. I think I probably have an error in my NAT settings. On my other two clients I defined the tunnel subnet (10.0.3.1/24 and 10.0.12.1/24) in the OpenVPN settings, and these were automatically added in Outbound NAT. The StrongVPN gateway is dynamic so nothing is added in NAT. The tunnel comes up with an address of 10.8.2.118 with a gateway of 10.8.2.117, so I have tried adding 10.8.2.0/24 in Outbound NAT with translation to the WAN address (as the automatic rules were created for the other tunnels) and also tried adding NAT from my local subnet translated to my tunnel interface, but neither makes a difference. I get internet access but through my default gateway (as verified with whatsmyip.org). My setup is below. Any help would be appreciated! I have tried to follow this thread as best I can but some of the images are now gone and most of the setup is for older versions of pfSense. I did try changing to AON on NAT but this didn't make any difference either.
