Hi All,
I have a customer is asking me the below questions, could you please help me out with.
I am planning to deploy the test RUT240 (4G) into a production site for some further live tests, and locking down the configuration before rolling it our to all our new sites. We require port forwarding rules configured so our cloud servers can interact with site equipment. I have the usual port forwarding rules working fine with setting “Any Source IP”.
Question1: But when I try to lock down a port forwarding rule to accept traffic from a particular source IP, I cannot get it to work (example setting screenshot below). I have tried a number of endpoints to no avail. Is there some other setting in the router, that I have overlooked to enable this ?
Question 2: Is it possible in the system logs to record Firewall rule matching? I cannot seem to find any log setting that records this. This is a useful feature so we can see what firewall rules are matched or not and the source IP; port etc? This is possible in other routers, like even the most basic standard Netgear. I used a Netgear to test and verify the source host IP rules.
Question 3: The manual/Wiki suggests :
Source IP address |
ip; Default: " " |
Matches incoming traffic from this IP or range of IPs only |
Source port |
integer [0..65535] | range of integers [0..65534] - [1..65535]; Default: " " |
Matches incoming traffic originating from the given source port or port range on the client host only |
External IP address |
ip; Default: " " |
Matches incoming traffic directed at the given IP address only |
External port |
integer [0..65535] | range of integers [0..65534] - [1..65535]; Default: " " |
S |
Assuming we can get 1 IP to work (Q1) What is the syntax to define a range of IPs?
Question 4: I am confused by the difference/meaning of Source IP vs External IP
Thanks in advance.
