Configuring VPN win7 clients with pfsense

johnpoz

Hmm also, so your pfsense box default gateway for clients on vpn side? If so then road warrior that uses the tunnel IP as its source should be able to talk to clients on the vpn side even with a dupe IP.

Site to site would be a major issue! But if the box on the vpn side is not using pfsense as default gateway - then again your not going to be able to talk..

So I notice you point dns to 192.168.1.1, but in your address bar your access pfsense at 192.168.1.254.. So this box your trying to talk to at 192.168.1.1 in your traceroute - is his default gateway off 192.168.1.0/24 the pfsense box at 192.168.1.254?

What is this 192.168.1.1 box? What is his default gateway?

What is this 192.168.1.1 box? What is his default gateway?

Look

my remote network (my office) 192.168.1.0/24
DNS,DHCP server 192.168.1.1
Default gateway 192.168.1.254 (pfsense box)

Tunnel network (as you saw before) 192.168.1.200.0/24

my local network (my house) 192.168.10.0/24
DNS,DHCP server 192.168.10.1
Default gateway 192.168.10.1 (a gateway , there is no a pfsense box)

with that settings should be able to see all devices on the remote network ? (because i will try them tonight )

thank you

johnpoz

Yes there should be no reason why you can not access stuff on the remote network, unless they are running host firewalls?

If youh have problems, please show your connection info and route print. And traceroute

Hi…also nothing happen and as usual i could ping only pfsense box and i could't see any device on the remote network...(i forget to what you said to me about print route command but tonight i will post it here)

but i want to ask you : what rules need i to and on which will i apply them (WAN,LAN,vpnServer) ?

thank you .

johnpoz

You shouldn't need any special rules - so unless you have changed the defaults your fine.. Did you run the openvpn wizard so it created your openvpn rules… here are my rules.

Now I did open up my lan rule to have * source vs lan net, but I don't think you really need to do that.. I had that as test I think for something else. While at work today I will change that and verify access to lan, etc.

And you would need Wan rule to allow your openvpn connection - but your stating that your connecting, so I have to assume you have that rule in place or you would never connect.

To be honest, you run the wizard for the openvpn and put in the info and your done! You should not be having so many problems.

Hi…i could ping only linux machines (from my house) but i could't see them (i mean : start logo,computer,network,here there is no any device a printer a server...etc,only my machine .)

and (from my office) i could ping that machine on my network (my house) from only linux machines

and please take a look below :

"but i could't see them "

And when do you think linux machines are going to show up in a windows browse list?? Are the running samba and participating in that nonsense?

If you can ping 1 machine on your work network from your vpn client, then you have access to the network - other machine not resolving or not answering ping is unlikely to have anything to do with the vpn connection.. More like firewall blocking it at the host or maybe its OFF? ;) As to resolving via host name only, your not pointing at pfsense for dns - so what does that IP your pointing to for dns run. Query it directly for hosts you want resolve? Do they resolve?

If you want boxes to show up in windows browse list across segments then your going to have to run wins! And even if on same network – it can take 45 minutes for a browselist to populate..

I would suggest you read up on how windows browselist work -- and again they have NOTHING to do with network access, file sharing or name resolution - NOTHING! Its a BS little list that is not real time, is not very stable and does not work across network segments, etc. etc..

Troubleshooting Computer Browsing on SOHO Networks with Microsoft Windows

Pfsense and openvpn have nothing to do with this - and your not pointing to pfsense for your name resolution for your vpn clients, so it has nothing to do with that.

You can ping a machine across your vpn connection - therefore your vpn is UP!! There is NO point to the browselist in the first place, use name resolution to resolve your computer names be it dns, wins or broadcast which is not going to work in your current setup. You don't know the names of the machines you need to access? Then what the hell your accessing the network in the first place for??

But sure if you want to get the browselist to work across segments then your going to have to run wins, and understand how it works. Good luck, its a pointless endeavor ;)

If you wanted the network browse list to work, you would have to create a bridged vpn where your road warrior got an IP on your lan and then browselist would work.. But it would most likely take at min 15 minutes to start to show anything, upwards of 45 minutes. I would assume your box thinks its the master browser for the segment it came up on, and whatever your workgroup name is.

Why do you think you need or even want a browselist? Now what you can do it query your work networks browse master for a list.

So for example using browstat, don't believe it will work on 7x64. You can do a browstat dumpnet and get your transports, one would be your vpn device, then you use that to query the browselist on your work network...

D:\Dropbox\tools>browstat dumpnet

List of transports currently bound to the browser

1 \Device\NetBT_Tcpip_{46B7FF42-B5F2-44F2-9EAE-1F0BAF7B4932}
2 \Device\NetBT_Tcpip_{791A8563-34BD-4681-A0F6-281494D295C8}

You can see which one it would be by mac, so I have highlighted the mac portions

Ethernet adapter ovpn:

Connection-specific DNS Suffix . : local.lan

Physical Address. . . . . . . . . : 00-FF-79-1A-85-63

\STORAGE NT 06.01 (W,S,NT,SS,PBR,BBR,MBR) My storage server
\W7X64-VM NT 06.01 (W,S,NT)

Those are the 4 boxes on in my home network that are participating in the browselist. No its not listing my linux boxes, they don't have samba installed - no its not listing pfsense, etc. etc.

I know that \storage is my browse master, since I have setup my network that way. Not really a fan of the browselist, just don't see the point of it. But there is always a way to skin the cat.. Just not seeing why it matter if you can browse your remote network?

But why i can't ping any windows machine ? (only linux machine)

LeCygne

Also i can't ping my printers , only linux machines .

johnpoz

Do you printers have a gateway set? Most likely not would be my bet. The windows 7 firewall by default blocks ping would be my bet as well. Kind of hard to answer a ping that is from a different network without a gateway.

If you can ping 1 box on your network, then clearly your vpn is up. What settings to you have on your windows firewall. Can you ping your windows 7 boxes from other machine on the local network? If so check that their firewalls allow ping from networks other than the local one.

Look my machines firewall is disable but there is a kaspersky program.

Yes i can ping windows machines from other .

johnpoz

Well check it for firewall – what part do you not understand that your tunnel is up.. Why would pfsense allow traffic from linux boxes but not windows boxes?

So if you can ping 1 box inside your network, and others don't respond - then its something on those machines.

until now nothing happened with windows machines

Also i disabled windows's firewall , but also no luck .

Set their firewalls to allow whatever traffic you want to use from your tunnel network.

Disable whatever firewall your running on those boxes.

johnpoz

I don't know - is it, is that is what is firewalling your traffic?

I am not sure why the thread is still open? You have verified your tunnel is working.. So now your issue is with clients, that has nothing to do with pfsense.

Look man this is the last step of my story…don't tell me to close this thread right ?i'm still looking for a solution for my problem your solution is not complete...

thank you .

johnpoz

I can not help you without info!! Did you uninstall your firewall software on the client? Did you configure said software to allow for the traffic you want to allow icmp, file sharing from IPs other than your local network?

Do these clients use pfsense as their gateway?

You clearly have a working vpn tunnel if you can access linux boxes behind your pfsense.. So my point is this is no longer a VPN issue but a client configuration issue.. This board is more for helping users with pfsense related issues - your issue is client related.

While I don't mind helping you, not much I can do further. Do I need to step you through verification that the packets are getting to your client via sniffing the traffic?

Tell you what – if you provide me vpn access to your network and login to pfsense box. And then out of bound access to a windows client I will fix the problem for you. Teamviewer works nice as an out of band solution. I will document what was the issue and show you the fix, etc. That would be must faster than us going round and round in this thread, not getting anywhere. If there is some other issue at play, I should be able to identify the problem within a few minutes.

But since you can access linux based boxes on that side of the tunnel - it really really points to a problem on the client box on your pfsense side of the network.

That's the end of my story
