Dear All,
I’m an ex DDWRT (R7800) user, i.e. …. a newbie in OpenWrt 
I changed the ISP (to a new IPv6 PD/56) and moved to OpwerWRT(Flint2) 24,10,5
GOAL
I run a NextCloud server (on ubuntu 24,04) at home, with a registered domain,
As I did before with DDWRT and IPv4 
, I need to access my server using the domain name (www.cloud5.it)
from home lan AND from outside,
PROBLEM
I followed onemarkfifthy youtube videos to learn something about OpenWrt and IPv6, and set the Flint2-OpwnWrt router as edge router.
I successfully set the PPOE connection, BUT cannot manage to have the web server recognized by hostname in the lan AND in the internet.
What I TRIED
Network → Intefaces →lan (advanced):
set the ip assignment to 64bit, removed the use default gateway, assign the prefix hint to “a” (from onemarcfifthy this should lead to a final subnet without any more subnet, and should help the router defining the ipv6 addresses)
Network – DHCP and DNS → Static leases :
Added a static lease for the server linking the IPv4 address to the MAC address, setting the ipv6 suffix, and setting the hosname
Network → DNS Record → Hostname tab:
Set the same hostname to the same ipv4 address
Tried to disconnect and reconnect the cable to renew the lease….
FAILURE:
-
from lan I can reach the server with the hostname ONLY if before I get it by IPv4 local address (if I try at first the hostname in the URL the site is unreacheable. Seems the browser is solving the problem….)
-
the web server do NOT get a global IPv6 public global static address
-
if I test my ip, the recognized ipv6 is NOT the global dynamic noprefixroute, BUT the scope global temporary dynamic… seems I have NO ipv6 public global address…
-
not having a public address, I cannot set a AAAA record with my registar) (as in the log, the suffix create ONLYa global dynamic noprefixroute)
HELP !!!
I attach a copy of the
- OpenWRT: /etc/config/dhcp
- server: ip a command
- server: /etc/host and /etc/hostname
THANKS in advance for any help !!
