I connected with my second router with wlan ( wwan ) to my main router. On my second wlan router, I have installed a samba server. The wwan get an ip from my main router. The lan IP of my second router is 192.168.1.1 and when I use nmap on 192.168.1.1, I can see, samba ports are open. Thats good.
But when I use nmap to wwan ip, I see samba ports are close. The ssh port are open on 192.168.1.1 and the wwan ip.
I have disabled my firewall on the second router but I have still the same issue, samba ports are only available.
By default, samba only listens on the lan interface. If you need to access the service through another interface, you must set it in the configuration file, e.g.
option interface 'lan wg0'
[global]
netbios name = OpenWrt
display charset = UTF-8
# interfaces = lo br-lan
interfaces = lo br-lan wwan
That makes no difference.

By the way ... there is a relayd bridge ...
Modify /etc/samba/smb.conf.template like this
[global]
netbios name = |NAME|
#interfaces = |INTERFACES|
interfaces = br-lan 192.168.10.155/24
server string = |DESCRIPTION|
unix charset = |CHARSET|
workgroup = |WORKGROUP|
and restart the service.
Check the listening interfaces.
netstat -nlp | grep '\:139\|\:445'
On the device 192.168.10.155:
root@OpenWrtDach:~# netstat -nlp | grep '\:139\|\:445'

tcp 0 0 fd91:f152:16be::1:139 :::* LISTEN 14175/smbd
tcp 0 0 ::1:139 :::* LISTEN 14175/smbd
In my case, thats the trick:
interfaces = lo br-lan 192.168.10.0/24
restart the samba service:
service samba restart
and u can see:
netstat -nlp | grep '\:139\|\:445'
tcp 0 0 127.0.0.1:445 0.0.0.0:* LISTEN 2333/smbd
