Trying to get LAN access, can only ping myself

ace_ventura

I am trying to setup an OpenVPN connection so I can have LAN access from a remote location. I am trying to get away from the easy but insecure PPTP VPN.
I am using release 2.0.1 (i386)

I have attempted to follow steps I have found online and YouTube and while I was successful in getting it to connect back to home and it gets an IP of 192.168.2.6, I can not access my internal LAN. On the client I can ping myself at the DHCP IP that the OpenVPN server gives me (192.168.2.6.) but I can not ping the pfsense box and OpenVPN server itself at 10.0.0.1. Nor can I seem to ping any other IP in the 192 range like 192.168.2.1 or 192.168.2.5. I have turned off the client windows firewall just in case. I have attempted to put in push "route 10.0.0.0 255.255.255.0"; but this does not work.

The client has OpenVPN v1.0.3 installed and exported settings from the OpenVPN gui on the PFsense box.

What more information would you like me to provide in order to be of better help?

Thanks.

Obfuscating private IP addressees and particularly netmasks is pointless and makes helping difficult.

Sorry, fixed.

So your using 192.168.2.0/24 as your tunnel network? Thats prob not very good idea since thats a very common network. What if your remove is on a 192.168.2.0/24 ?

what boxes would you ping pinging at 192.168.2.5? or 2.1?

So 10.0.0.0/24 is your pfsense lan network? What OS are you running the client on? If windows 7 for example you need to run the client as admin to get the pushed route.

Yes I am using 192.168.2.0/24 as my tunnel network, we use the 172 network here at work and I use the 10 network at home. Should I change my tunnel network to 10.0.1.0/24?

I thought I would try to ping 192.168.2.5 or 2.1 as a DGW since I received an IP of 192.168.2.6 but I knew it probably wouldn't work, just thought I would put that information out as well even if I didn't need to, more a quick here lets try this thought that went through my head.

Yes I use 10.0.0.0/24 as my pfsense lan network.

Client OS is Windows 8, Yes I have run the client as admin.

anyone?

Post client config, server settings, firewall rules from openvpn tab, routing table from PFsense and routing table from client when connected.

Hi,
I've got the same issue , i just can ping my pfsense box but i cannot ping my Wifi Box.

I use remote access 1.0.3 SSL/TLS + User Auth

in my firewall's rules nothing is blocked.

my config is :
dev tun
persist-tun
persist-key
proto udp
cipher BF-CBC
tls-client
client
resolv-retry infinite
remote myipaddress 1194
tls-remote Proxiel Server Cert
auth-user-pass
pkcs12 doberman-udp-1194.p12
tls-auth doberman-udp-1194-tls.key 1
comp-lzo

My lan on my pfsense box is 172.16 and openvpn give me 10.0.8.0

to the openvpn server i route the network 172.16.0.0

so i don't know where do i search…..

if you have any idea ;)

Thanks.
Myke.

Your running version 1.03 of pfsense? Or is that the version of the openvpn gui your running?

What client are you on? Windows 7 unless you run openvpn as admin it won't create the route.

So I have been running pfsense since the 1.x version and development snapshots on 2 and 2.1 and have never had any issues with openvpn.

What remote network are you on? So you run 172.16 /?? /16?? on your pfsense lan? That could easy be in conflict with what your remote network is.

Please post your full server config, can be found in /var/etc/openvpn server.conf – there should be a .conf file there for your server settings.

Also post your route table from your client once you connect and what if any firewall rules do you have in place on pfsense? What is in your openvpn tab? Where does your wifi box sit? how is it connected to pfsense - you sure your ping is just blocked on host firewall your trying to ping?

Thanks Johnpoz for your answer.

My version of pfsense is 2.0.1 and my remote network openvpn is 2.2.2. i'am administrator of my computer ( window 7 ).

My pfsense lan is 172.16.0.0/21 and my network in the office is 192.168.0.0/24.

In my firewalls logs i see my ping is ok but no responding.

I can just access to my pfsense and i don't have internet.

I will post full server config tomorow.

Thanks for the help :)

ace where is your route table - this shows that addition failed

well in your first post you had no route - so no your not going to be able to get to anything on the other side of the tunnel.

In your second post you did, so that makes sense why its working now, and was not before.

Why would you trace to my 192.168.1.100 address??? Did I really have to spell out to use an IP on your pfsense lan vs my example ;)

ace_ventura

haha because i was on call at the time and not really paying attention to what i was doing, lol i'm sorry I feel like an idiot.

I'm guessing its because the client wasn't run as administrator, which is odd since I explicitly told it to the first time.

just for giggles ill prove myself now LOL
