IPsec VPN Site to Site (Sonicwall <-> pfsense)



  • Hey guys,

    I am trying to set up a vpn between different offices of the company I work for.

    I have already made the settings, but I have an error in the logs:

    Jun 13 10:50:37 charon 05 [IKE] <con1 1="" |="">received INVALID_SYNTAX notify error
    Jun 13 10:50:37 charon 05 [ENC] <con1 1="" |="">parsed IKE_SA_INIT response 0 [N (INVAL_SYN)]
    Jun 13 10:50:37 charon 05 [NET] <con1 1="" |="">received packet: from 49.X.X.X [500] to 189.x.x.x [500] (36 bytes)
    Jun 13 10:50:37 charon 11 [NET] <con1 1="" |="">sending packet: from 189.x.X.X [500] to 49.x.x.x [500] (396 bytes)

    I want to assume that there are some different configurations of the sonicwall side.

    Someone has already done this type of configuration that can give me directions or advice.

    Greetings.</con1></con1></con1></con1>



  • Hi Trasher, we use sonicwalls for all our offices and pfsense for the main server location, what setting are you using?



  • I'm trying to set up a point-to-point vpn.

    In the main office, I have a sonicwall and in the branch office I have a pfsense latest version.

    The case is that I have configured the vpn options on the sonicwall side and the pfsense side, but I can not get them to communicate.

    I have already configured rules on both sides of the vpn to allow access to the information, the logs do not show any blocking.

    See attached images.

    In pfSense go to Firewall>Rules>IPsec>add action pass and everything any to any, click save/add



  • Hi all,

    I'm having a similar issue. I'm trying to connect PFSense to a SonicWall and just can not seem to get it to work. Any help would be greatly appreciated.
    I've attached a bunch of screen shots of the configuration on both sides as well as the error message I'm getting from PFSense.

    Thanks



  • I have done it like below (full testing was not possible) and it seems to work:

    I have put in some additional rules on the WAN Interface, see screenshot.
