OpenVPN connection reset



  • Hi,

    I know it's not the first thread about this but I can't find any solid solution.

    I configured OpenVPN on pfsense 1.2, it went fine for about 1 week then all clients have their connection reset every 5 seconds.

    I have only 4 clients, each with their own certificate build with 'build-key-pass'.

    I was running openvpn on tcp 1194 when the problem appeared, now I switched to udp 1194 and the problem went away…

    Here's my server config file

    writepid /var/run/openvpn_server0.pid
    #user nobody
    #group nobody
    daemon
    keepalive 10 60
    ping-timer-rem
    persist-tun
    persist-key
    dev tun
    proto udp
    cipher BF-CBC
    up /etc/rc.filter_configure
    down /etc/rc.filter_configure
    server 10.0.10.0 255.255.255.0
    client-config-dir /var/etc/openvpn_csc
    push "route 172.20.0.0 255.255.0.0"
    lport 1194
    push "dhcp-option DOMAIN TDA.local"
    push "dhcp-option DNS 172.20.0.51"
    push "dhcp-option DNS 172.20.0.52"
    ca /var/etc/openvpn_server0.ca
    cert /var/etc/openvpn_server0.cert
    key /var/etc/openvpn_server0.key
    dh /var/etc/openvpn_server0.dh
    comp-lzo
    persist-remote-ip
    float
    
    

    Here's a sample client config

    float 
    port 1194 
    dev tun 
    dev-node ovpn 
    proto udp
    remote xxx.xxx.xxx.xxx 1194 
    ping 10 
    persist-tun 
    persist-key
    tls-client 
    ca ca.crt 
    cert yannickg.crt 
    key yannickg.key 
    ns-cert-type server 
    comp-lzo
    pull 
    verb 4
    
    

    Any help will be appreciated!

    Thanks
    Bye
