Host DNS

Carlos Cuestas

Hi,

 

Host objects dns do not change from ip when the host goes from a lan network to a wifi network or from wifi network to lan network, this causes the navigation accesses (social networks, streaming, etc.) to stop working when the host Has the network changed? what should I do?

    Use a dns host object instead of a host object.  The up is then determined by dns lookup

    I would be curious why you need an object definition for a device that moves around.

    Hi, I'm using DNS Host objects but we've noticed that when the DNS host disconnects from the wired network and connects to the Wi-Fi network, the access to the restricted navigation to social networks and streaming stops working.

    we have reviewed and found that when the host dns has a different ip in the DNS to which it registers in the UTM, the accesses to the navigation stop working, that is to say that UTM takes time to update the host ip.

    You probably need to elaborate on your design.  A few ideas to evaluate.  D.N.S. caching is pretty normal.

    If UTM does your DHCP, it should not have the delay caused by caching DNS results from elsewhere.

    If DHCP is done elsewhere, can you do reservations and lock down to the two possible addresses?

    Or can you contril based on user instead of device?
