Hi,
First, excuse my english, i'm french :)

For test purposes, i had to install a samba server on a distant server for work. Everything works fine.
My issue is to deal with access restrictions: I use "host allow" command in the smb.conf, wich works fine when I use my client ip address, but client ip address change frequently. I had the idea to use a dyndns such as "no-ip" to retrieve changing ip with an http factor.
But it seems that "host allow" option from samba does not resolve the ip with that factor, although he recognize it. here is an extract of the log where it recognize my connection (replaced some infos by x):

In my smb.conf:

hosts allow = xxx.ddns.net

[2021/10/08 16:08:09.519621, 0] ../source3/lib/access.c:338(allow_access)
Denied connection from areims-xxx-x-xx-xx.w90-7.abo.xxxxxxx.fr (90.x.x.99)

the ip that semba regognize is the right one, but deny the access...

Someone could help with a hint?
Thanks in advance
