Same IP Address Problem

nicholasrudd

So I have a some computers that are trying to connect to a OpenVPN network so they can join and log-into our Active Directory Domain Controllers, however I noticed after setting up two or more computers that after a new computer logins they all receive the same IP address, and then receive a "[server]Inactivity timeout (--ping-restart] received, restarting" (this is what tunnelblick states, dont know about Openvpn for Windows) in the clients log, I am guessing this is due to a the keepalive on the openvpn server trying to ping that computer when another computer has its IP, this would not be so bad if it would flush/drop the openvpn dns servers when it does fail but since it does not, it results in the clients simply losing internet all together. Please note that this happens when I am on Windows or Mac, Linux has not been tested.
Here is my server conf

port 1194
proto udp
dev tun
sndbuf 0
rcvbuf 0
ca ca.crt
cert server.crt
key server.key
dh dh.pem
topology subnet
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 172.31.0.237"#Main Active Directory Domain Controller
push "dhcp-option DNS 8.8.8.8" 
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify crl.pem
keepalive 5 30

Any help is welcome

my client list (the only log in /etc/openvpn) is

OpenVPN CLIENT LIST

adclient,[myclientip]:52692,358915,3028017,Fri Apr  1 22:51:09 2016

END

And when I run

grep VPN /var/log/syslog

I get

Apr  1 18:52:32 ip-172-31-0-150 ovpn-server[1096]: OpenVPN 2.3.2 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [PKCS11] [eurephia] [MH] [IPv6] built on Dec  1 2014

Sorry, kinda new to openvpn, however after reading the log output, it indicated that it was only letting one computer on at one time and it I wanted multiple to add duplicate-cn to my server config
