Pfsense openvpn & dd-wrt openvpn site-to-site

  • Hello everyone, I need to set up a site-to-site network (OpenVPN)

    site A:pfsense2.3.1  Servers
    Server mode: Peer to Peer (SSL/TLS)
    Protocol: UDP
    Device Mode: tun

    site B:DD-WRT Clients
    Protocol: UDP
    Device Mode: tun

    After setting, VPN connection fails, the following log appears every one minute:

    Sep 7 12:35:45 openvpn 40135 Initialization Sequence Completed
    Sep 7 12:35:46 openvpn 40135 send_push_reply(): safe_cap=940
    Sep 7 12:36:46 openvpn 40135 [test] Inactivity timeout (–ping-restart), restarting
    Sep 7 12:36:46 openvpn 40135 SIGUSR1[soft,ping-restart] received, process restarting
    Sep 7 12:36:48 openvpn 40135 NOTE: the current –script-security setting may allow this configuration to call user-defined scripts

    Then change the Server mode: Remote Access (SSL / TLS)
    VPN can be connected to normal,But can not meet the requirements of the site-to-site

    Please help me, thank you
