Configuring VPN win7 clients with pfsense

firewalluser

I havent been able to get OpenVPN using TAP to work either as you can see from my post here http://forum.pfsense.org/index.php/topic,58724.0.html

I have got TUN working though, I can ping the pfsense firewall, ping other devices on the network and can even remote access onto my Win7 desktop and SSH to my linux servers from inside the lan.

It might pay to use TUN for now as I have seen some comments on this board that 2.0.x has some issues which might be affecting the TAP/Bridge mode, but these should be resolved when 2.1 is released. Alternatively you could try a beta of 2.1 if you fancy the risk.

Guys…i'm waiting you .

Waiting for what?

So now your pfsense has public IP on its wan? Then run through the openvpn wizard and your done.. Not sure what else you think you need to do?

What is not working now?

I'm waiting for this :i could see any device on my network (servers,printers,etc) .

Yeah once you vpn in, depending on what firewall rules you put in place you can access anything you want on your network. I vpn into my home network pretty much every day. I am on now - yes I can print to my printer if I want, I can remote desktop to any box on my network, I can access my file shares, etc. etc. etc.

So tell me what are rules will i use ?

thank you .

johnpoz

You wouldn't use any rules really unless you want to limit or block something - wizard should create the default rule

IPv4 * * * * * * none OpenVPN pfsense wizard

The above is what I have in my openvpn tab

What is subnet' ip address are you using and for vpn' clients ?

johnpoz

You can use whatever you want.. I use 2 different ones for tcp or udp connections I use

NO TCP / 443 10.0.200.0/24 pfsense tcp
NO UDP / 1194 10.0.8.0/24 pfsense udp

Just use something that is unlikely to conflict with the network segment connecting to you.

So why i could not see any device on my network also i can't ping any device except my pfsense ?

i have a rule like your rule on my WAN and LAN

Are we to just guess your setup? For all I know you have host firewalls blocking ping. What does could not see mean? Are you talking like a windows browse list - thats not going to happen over different segments and a nat. You could run a wins server if you want to have browselists across segments.

For all we know you have 192.168.1.0/24 on your pfsense lan side and remote network is also 192.168.1.0/24 – are you sending your route, is the client getting the route?

Post up your openvpn config, did you do a traceroute from the client that could not ping your pfsense box? Is he sending the traffic down the tunnel?

tunnel network : 192.168.10.0/24
my lan:192.168.1.0/24

after connecting to my network i got 192.168.10.6 (windows told me that )

after that i can ping only pfsense box

tell me exactly what are you looking about openvpn confi because there are many fields with vpn confi .

Also about i could't see any device i mean at least i ping them (my devices:pritner,computers,servers)
and sharing files .

i hope what i told you to be helpful .

thank you .

johnpoz

And where are you connecting from? What is that network?

Post up output of route print after you connect.

Do a traceroute to the IP your trying to ping.

So what if there are multiple fields, here attached is mine.. And then the client config from client export. Just snipped out part of public IP for privacy.

And what part do you not understand about this???

WARNING: potential route subnet conflict between **local LAN [192.168.1.0[/b]/255.255.255.0] and **remote VPN [192.168.1.0[/b]/255.255.255.0]

Your networks on both sides are the SAME!!!! NOT going to work!!

You have

192.168.1.0/24 –- tunnel --- 192.168.1.0/24

Does not work like that.. Even if client that is directly connected to the tunnel sends his traffic down the tunnel. And a client on the vpn side sees the traffic - its going to be from a 192.168.1.0 address, never going to send it back to pfsense because that is the vpn boxes LOCAL network, no need to talk to pfsense.

You need this

192.168.A.0/24 –- tunnel --- 192.168.B.0/24

You can not have the same network on both sides of a tunnel and expect it to work without doing some fancy NATing of the connection.. If your remote network is 192.168.1.0, make your local network 192.168.72.0/24 or something - that is unlikely to be used anywhere that would be remote into your network.****

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?

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
