draytek cctv through firewall

Ok guys

I am trying to get a cctv ports 82 and 9000 tcp/udp working I am getting on a open ports scanner

Host is up (0.11s latency).
PORT    STATE         SERVICE
400/tcp open          work-sol
401/tcp open          ups
400/udp open|filtered work-sol
401/udp open|filtered ups

my port redirects are 82-> 400
and 9000 to -> 401

but udp is open filtered which kind of says the firwall needs a rule for ports 82(400) and 9000(401)
am I correct in this assumption

as I need the cctv access to outside

ok I found out 400 is not good its used by virus's over udp so the firwall was filtering 400 so I found unused ports and choose those and it worked

so 82 for web and 9000 for media  open port

or 40 for web (port 40 unused) and 4 ( port 4 is unused) for media port redirect

From its FAQ and "Open Port Setup"  article maybe that can help in Port Forwarding

How do I open the Firewall in my Vigor Router to allow access to computer / device on my network from the Internet?

Assuming the computer / device on your network has a Private (NAT'd) IP Address, you need to use the Open Ports Setup in the Vigor to allow access from the Internet. You do not need to use the IP Filter/Firewall Setup.

But I thought on drayteks website instead on using open ports or redirects use cms as thats the new way ?

I am not a draytek user hence none the wiser but I see the qns as general exposing internal service to external. Better to clarify with support if you are a user

I found out 400 and 401 where bad choices for udp as virus' use them as udp is stateless so the firewall was filtering if I choose a port like 4 that is not used by anything it works
