Unable to connect via mobile user vpn ssl

I try to connect from an external computer to the firebox of my company with the watchguard mobile vpn via ssl.

When I am at my office, I am able to connect using the firebox ip address and the port used for the vpn example and the username / pass .

But when I try to connect outside of the office using the ip adress of the company, the port and the credential of the user. It is impossible to connect.

Here is the log :

    Hi @Seb1978 is the internal IP of your firewall -- you'll need the external IP of your firewall to connect to it externally.

    When you're in the office, try going to a site like ipchicken.com, and see what address you get back. That will be your external IP.

    This is what I did with whatismyipaddress.com and it gave me

    The address I am using, like you can see at the start of the log.

    It is also the address that I see next to the eth0: external (DHCP) on the watchguard system manager.

  • 1) consider opening a support incident on this t get help from a WG rep.
    Select SUPPORT CENTER above, sign in (if needed) and then Create New Case.

    2) You can turn on diagnostic logging for SSLVPN which may show something to help in Traffic Monitor:
    In WSM Policy Manager: Setup -> Logging -> Diagnostic Log Level -> VPN -> SSL
    In the Web UI: System -> Diagnostic Log
    Set the slider to Information or higher

    A WG support rep will probably want to see these too.

  • Also, I suppose that something could be blocking TCP port 442.
    The next log message should be -
    TCP connection established

    Traffic Monitor diag logs may well help here.

  • The good news is that your SSLVPN web login page comes up on the IP and port 442. Test logging into that first.

    Hi @Seb1978

    The VPN client is probably getting that internal IP from somewhere.

    If you go to
    (in WebUI) VPN -> Mobile VPN, Click on Mobilr VPN with SSL -> Configure.
    (In Policy Manager) VPN -> Mobile VPN -> SSL

    Under Firebox IP address, please make sure whatever IP you're connecting to externally is entered here. If isn't here, please put it here, save, then try again.

    Thakn you,

  • I can access the login page at

  • Everything is working the problem was address. I was trying to use a backup address!! Once I put the ip has the primary, everything worked fine!!
  • A support incident or diagnostic logging is next

  • Regarding "In Policy Manager) VPN -> Mobile VPN -> SSL

    Under Firebox IP address, please make sure whatever IP you're connecting to externally is entered here" comment, the SSLVPN actually does work with completely bogus domain names entered there. For testing, I set mine to "vpn.completelybogusdomain.net" and the backup to "sparky.nowheredomain.com" and then used my WAN IP to connect to the SSLVPN. Of course, it pops up a certificate warning window, but goes ahead and connects if that windows is approved.

    I was curious, so I tested.

  • V12.5.3 is just out today with this fix:
    . The Mobile VPN with SSL client can now connect to the Firebox backup IP address when the primary IP address is unavailable. [FBX-16284]
