DHCP over OpenVPN
-
I have OpenVPN set up on my pfSense router and it is working great, if only one client is connected through the vpn. If a second client connects they fight for the same IP. My OpenVPN dhcp pool is set to 192.168.100.0/24 but any client that connects gets 192.168.100.6. Please advise.

Same deal with my vpn Server, help!!! I just lunched this server friday and I have users calling me they can't connect. The problem is they are all getting the same ip address 192.168.2.6 my address pool is set to 192.168.2.0/24 ???

Are you guys using SSL (shared key) mode? In SSL mode, only one client can connect to the VPN. There's no such limitation if you guys use TLS (PKI) mode, though.
In case you guys are using PKI mode and it still doesn't work, please post your openvpn_{client,server}X.conf.
-
I'm using PKI mode, where do I find the openvpn config file in pfsense?
-
Any One?
-
it does not help you when you know where the config file is stored since it is automatically generated and your own file would be overwritten.
you can change everything that stands in the config file on the config page of OpenVPN itself.
either through the GUI or in the field: "Custom options"
if you just want to have a look at the config-file it is here:
/var/etc/openvpn_server0.confcan you see the different "Common Names" who are trying to connect when you look at the OpenVPN log?

I found what my problem was, when I was creating my client certificates in the common name I was entering the same name myserver.mydomain.com thinking this was refering to the openvpn server name.
I created my certificates with different common name and now it works.Thank you gentlemen. ;D

Hi sbarreros,
I'm also have a problem same yours. What's actually u change? I'm also do like yours above, give a different name for Common Name (for client certificates), but it's also same. Both client if wanna access OpenVPN server will get the same IP Address.
Thus will give this kind of error :
"
NOTE: FlushIpNetTable failed on interface [65539] {3890476B-0667-4DE4-832E-0FB996C0862A} (status=1413) : Invalid index.
