RAX200 - Restricting Port Access to external IP Range
Apologies for a long preamble on this. Problem: I have a streaming camera which works. I can see it on my home network all the time. I use a streaming service based in the USA, and I can embed the...
I have the latest firmware - V1.0.10.140_1.0.79.
The Modem is a Virgin Media Superhub 4 (set to modem mode). It isn't a problem with that.
There are no cabling issues. Everything works, and there are no hardware issues.
The camera is permanently visible on my home network. The problem is purely to do with ports 'closing'. As in ports open, camera streams, but ports closed, camera doesn't.
The only issue is those ports repeatedly - between 2-10 times a day - appearing closed from the outside, whilst appearing open from inside. They close and re-open themselves (from the outside) when Armor is enabled, but remain open continuously when Armor is disabled. They opened immediately during a closed period as soon as I disabled Armor. So it has to be concluded that Armor is making them appear closed (even when they are not, according to netstat).
I have been advised to restrict the port access (for port 554) to a specific IP range given me by my streaming host while Armor is disabled - and to see if doing that prevents Armor doing whatever it is doing when a port is scanned maliciously, or to at least afford some protection.
So my question is: how do I restrict access to a port to that range of incoming IP addresses (on the RAX200)?
Seems like a issue with Armor if the ports work properly with Armor disabled.
Yes.
My question is how do I restrict access to a port to a specific range of incoming IP addresses (on the RAX200)?Try setting up Port Forwarding on the RAX and disable uPnP...
I already have.
I have a functioning system with the necessary forwards. That functionality is affected by Armor. With it disabled, the system functions flawlessly. Except that there is now nothing there to block malicious scans.
My question is how do I restrict access to a forwarded port to a specific range of external IP addresses on the RAX200.
