OpenVPN Cliet Cannot Access LAN OpenVPN
-
I think that your problem is windows vista :D or your client cannot add route to system via IPAPI
Try add this to your Client configs :
route-method exe
route-delay 2but this (FlushIpNetTable failed on interface) is odd too and i dont know whats wrong…

Hi Bredys,
My Client using Windows XP and Windows 2003 Server. The one who can access the OpenVPN Server is client that using Windows XP. While user that using Windows 2003 Server can access OpenVPN Server but it will come with the error that I've already paste in the earlier topic.
Anyway I'll try with your suggestion. Thanks Bredys. I'll update later if this suggestion cannot work.
Anyone who can help me on this please…. :)

Nail up both clients and then show the output of these commands from a shell:
ifconfig
cat /tmp/rules.debug | grep tun
cat /tmp/rules.debug | grep tap -

That is strange. You should have two tun devices (tun0 and tun1) from what I understand.
Let me speak with Fernando.

Ok..For your info, my pfsense running on version 1.0.1-SNAPSHOT-03-27-2007.

Just for brevity sake, please upgrade to the latest and retest.

I've do add the command "route-method exe" and "route-delay 2" at the Client Configuration file. And u know what…The client can access the OpenVPN Server and also the LAN of it.
But it still appear some errors on it..

"What is actually the error…
Can i just ignoring it or i've to do something to fix it. The client now can ping the LAN after i adding the command....
One more...users actually can access the OpenVPN simultaneous? Like PPTP, the maximum concurrent connections is 16.....

I'll upgrade to pfsense 1.2 later. But what's actually they fix in the 1.2 version for OpenVPN?

There's no limit imposed by the pfSense OpenVPN implementation. There might be a limit in OpenVPN or this could also be limited by the maximum number of tun interfaces at a given moment in FreeBSD. But this limit is certainly greater than 2.
This could be a broken client, perhaps. If you're confortable with Unix, log into the pfSense shell, kill the OpenVPN daemon (openvpn process), edit /var/etc/openvpn_server0.conf and change the line that says "daemon" to "verb 4". Then start OpenVPN daemon by running "openvpn –config /var/etc/openvpn_server0.conf". Then try to connect from the clients.

How to kill OpenVPN daemon in pfsense..I'm not familiar with it..
I try to do edit /var/etc/openvpn_server0.conf configuration file without killing the OpenVPN daemon process.. but it appear some errors after i start running it back..

openvpn –config /var/etc/openvpn_server0.conf
Options error: Unrecognized option or missing parameter(s) in /var/etc/openvpn_server0.conf:15: lport (2.0.6)

Hi all,
Just wanna update with the current issue…I'm currently running 1.2-BETA-1 version...
I just get the solution for this problem...I change the user configuration from "route-delay 2" to "route-delay 10" and the OpenVPN can successfully accessing OpenVPN Server and also can ping the LAN.
float
port 81
dev-node vpn
proto udp
remote 10.10.100.223 81
ping 30
persist-tun
persist-key
tls-client
ca ca.crt
cert 21.crt
key 21.key
ns-cert-type server
cipher BF-CBC
route-method exe
route-delay 10
pull
verb 4Any info regarding this issue why some client can connect successfully without any problem and some clients need to change the configuration as above. Need feedback from the expertise..
Thanks…
