<p>I think you misunderstood me. Most broadband providers don't
offer fixed IPv4. Due to privacy considerations, even under IPv6
on normal connections, addresses will always change. (prefix) As
soon as an address changes and my dynamic DNS system registers it,
an IPsec or OpenVPN client on my phone can reconnect. (This
happens once a week).<br>
The Wireguard app simply lacks a monitor to see if the IP address
has changed. Therefore a ttl in the DNS was introduced .... (After
a registered loss of the connection - also shown in the log - no
DNS request is executed and the tunnel breaks down permanently.)</p>
<p>I think these are the most common scenarios with OpenWRT routers
...<br>
</p>
<p>Having a DNS entry does not mean that it always points to a
static ip, so when a tunnel disconnects, the Android-app itself
(userspace) should handle this like many other existing
VPN-Clients do by a re-query of the DNS entry...</p>
<p>My question is, is there any opinion on such an implementation?
Should i try to implement it into the android app and provide the
code? (Unfortunately i am not a good android app-developer)<br>

<div dir="ltr">You need to setup dns for your home site then use
that to connect. Or you need to synchronize the endpoint out of

is a general problem all software encounters.<br>

<p class="MsoNormal">Is it possible to integrate a function
