jai23155 why don't you provide details of your configuration so we can tell if you're suffering from exactly the same problem as you think, or if it's completely unrelated.

jai23155 · Feb 3, 2011, 6:26 PM

hi, my configuration
main office LAN-192.168.10.0/24 behind pfsense
looking to set up open vpn client for remote users. created certificates, keys and config files. open vpn server on pfsense box.
protocol tcp
local port 1194
address pool 192.168.12.0/24
local network 192.168.10.0/24
cryptograohy bf-cbc (128 bit)
PKI
disable netbios
lzo compression

tried from a pc which is outside lan, can connect to pfsense box, but neither ping any pc on LAN nor browse windows shares on server.
when connected it is giving a ip at web GUI. but there is no ip on interface when i did ipconfig /all, it is showing a self assigned ip (168.254.37.38).
the pc outside the LAN is server 2008 (i am testing from) if it makes any difference. when i tested it from my home (win 7 laptop), i can see the adress assigned on interface 192.168.12.6, dhcp server 192.168.12.5; but subnet is 255.255.255.252 rather than 255.255.255.0.
i am already running IPsec tunnel between two of our sites. there is no open vpn tab in firewall and no process running for openVPN.
please find attached to see my openvpn server config. thanks

The inability to browser shares has been discussed many times - that's usually down to attempting to use WINS on a routed network without using a WINS server.

Can you post a screenshot of the server settings and a copy of the client configuration file, as well as the client log.

jai23155 · Feb 3, 2011, 7:00 PM

please find attached server config.
client config:
client
dev tun
proto tcp
remote xxx.xxx.xxx.xxx 1194
ping 10
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert ovpn_client1.crt
key ovpn_client1.key
ns-cert-type server
comp-lzo
pull
verb 3
we are using server 2008 r2 as domain controller and wins server which is at 192.168.10.xxx.

Cry Havok · Feb 4, 2011, 11:57 AM

Can I suggest that you push the DNS and WINS servers for the LAN and set the NetBIOS mode to p.

If you're still having problems after that don't forget to post the rest of the information I asked for ;)

jai23155 · Feb 4, 2011, 12:22 PM

did what you said. but no use, still same result. i couldn't even see my open vpn service running in status or in firewall.
my client config is
client
dev tun
proto tcp
remote xxx.xxx.xxx.xxx 1194
ping 10
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert ovpn_client2.crt
key ovpn_client2.key
ns-cert-type server
comp-lzo
pull
verb 3
i am already running an IPsec tunnel between two sites. is there any ipsec opn client softwares, so that i dont have to struggle with openvpn.
thanks

As you're consistently not supply the requested client logs it's hard to help you. Of course, if you haven't started the OpenVPN service that might explain why it isn't working.

As for IPsec clients, there are some good options and if you look in the IPsec forum you'll find various options.

anyway, i got IPsec vpn client up and running in few minutes. but, i really want to know how to get open vpn up ?? thanks

The log shows the problem, and even links you to a FAQ entry telling you what to check - see here. If you're using Windows Vista or Windows 7 ensure you run the client as an Administrator (right click -> run as administrator).
