Amm, have you checked in LAN? in my case a similar thing happened and I can't access ports even in the same LAN. After checking with Advanced Port Scanner, it will show every docker port closed, although unraid ports are working:
Port 21 (TCP)
vsftpd Misconfigured
Port 22 (TCP)
OpenSSH 8.4 protocol 2.0
Port 23 (TCP)
Linux telnetd
Port 80 (TCP)
nginx
Port 111 (TCP)
rpcbind
Port 139 (TCP)
Samba smbd 3.X - 4.X workgroup: WORKGROUP
Port 445 (TCP)
Samba smbd 3.X - 4.X workgroup: WORKGROUP
I recently moved my entire network (including my router) to a new house (just a modem swap) and now I can't access my servers although anything that does not require a port seems to be working fine (everything on my VMs)
Any help is appreciated.
