Clients always get the same ip address

[poma]

I have an ubuntu openvpn server and a few windows clients. Clients access internet through NAT. Clients always get the same ip address so only one client can use the server. Here are configs:

Code: Select all

server 10.7.7.0 255.255.255.0
port 443
push "redirect-gateway"
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"

dev tun0
proto tcp
keepalive 10 120
comp-lzo
dh /etc/openvpn/dh1024.pem
ca /etc/openvpn/ca.crt
cert /etc/openvpn/server.crt
key /etc/openvpn/server.key

max-clients 10
status /var/log/openvpn-status.log
log-append /var/log/openvpn.log
verb 3

Code: Select all

client
dev tun
proto tcp
remote viking-studio.com 443
resolv-retry infinite
nobind
persist-key
persist-tun
ca viking_ca.crt
cert viking.crt
key viking.key
comp-lzo
verb 3

Do all of your clients use the same client certificate?

If not then making ccd files for each client cert should solve it.

Yes the problem was caused by multiple clients that used the same certificate. I've solved it by adding "duplicate-cn" line to server config

Glad you resolved it. Thanks for the follow up post.
