    3CX V14 Tunnel.

    I’ve changed my extension on tab ‘3CXPhone’ to use tunnel for remote connections.
    As I will be going to Dubai on Sat 3rd October.

    This has updated my iPhone client fine to use the tunnel.
    Tunnel works fine when offsite in UK.

    But when onsite and connected by wifi, I get service unavailable.

    I’ve worked out why, but need to know if there is any solution without disabling when in UK.

    Our install uses 2 LAN connections (Non-NAT).

    LAN1 (External IP) 84.19.*
    LAN2 (Internal IP) 192.168.*

    With the new version V14, you need FQDN Split DNS. Which works fine on none tunnel.

    The problem is you can only enable the tunnel on 1 IP address. So our External IP is enabled.

    When in the office, the FQDN is using the Internal IP so is unable to connect to the tunnel.

    Is there any solution to this?
