My ISP supports TR-069 auto management on router and this uses TCP/8089. The router already uses this port so I cannot map it manually.
Is there any option to change the default port? I have looked everywhere and cannot see it. Even if the local port remains 8089 on server can a port map be used on router and iOS app instructed to use a port other than 8089?
Alternatively can the server and app use IPv6? I have routed IPv6 and full IPv6 on LAN with no need for mapping or NAT. Almost all connections I use with iOS have full IPv6.
Thanks in advance.
