Hello,
I have a Mi Router 4 giga, SW version 2.28.132 .
I need to forward several ports to my outer network (ISP router, under my control, as well).
I forwarded several ports from my Synology NAS and notebook, all have static IP configuration on the Xiaomi router (working fine), but port forwards do not seam to work.
When I use nmap from the outer network (behind Xiaomi router), I see 2 forwarded ports instead of 10+ configured; I guess these are upnp configured, from the NAS - but even the upnp configuration has more ports set and I cannot access these. The other ports are not open and I am not able to connect to them. Any advice?
Thank you!

Just one router - correct?

Are all of the static IP addresses outside of the router's allowed DHCP IP address range?

Are all those static IP addresses reserved on the router via the devices' respective MACs?

What port numbers are you trying to forward?

Hi, thank you for your reply. Two routers. Schema:

........................NAS
............................|
NTB -- Xiaomi Router -- ISP router
...........................................................|
............................................NTB with nmap

Static IP addresses are within the DHCP range, but no conflicts.
Yes, reserved based on the MAC.
TCP+UDP: 5001, 6882, 6881, 9006, 3979
TCP: 5900, 5800
UDP: 3978

NMAP result:
5001/tcp open ssl/http nginx
5800/tcp filtered vnc-http
5900/tcp filtered vnc
67/udp open|filtered dhcps
68/udp open|filtered dhcpc
773/udp open|filtered notify
3702/udp open|filtered ws-discovery
5555/udp open|filtered rplay
10000/udp open|filtered ndmp
16862/udp open|filtered unknown
25003/udp open|filtered icl-twobase4
29823/udp open|filtered unknown
33744/udp open|filtered unknown
49503/udp open|filtered unknown
53589/udp open|filtered unknown
54711/udp open|filtered unknown
61961/udp open|filtered unknown

My goal is to forward ports for NAS on the xiaomi router and then on the ISP router to have them facing the Internet. Works for 5001, so far.
