Routing between a net and a subnet
-
Hi to all,
I work in an address space made by two contiguous C class (254 addresses) network joined by a 255.255.254.0 netmask for a total of 510 available static addresses.
Having to install three ip cameras, after many tests, I realized that their configuration software is able to assign to each interface only the 255.255.255.0 netmask. This is clearly a problem from many points of view.
The question is: is it possible solve this mismatch by using pfsense? And in the case, how?
Sorry for my english, and thanks in advance to all.chalten

@chalten Is there any reason you can't define a new 255.255.255.0 subnet specifically for your camera system in a different address space? Your router should be capable of routing between the them on the same hardware. For example I have a 10.10.10.0/24 and a 10.10.11.0/24 using the same network hardware and I routinely switch my machine between them when I need to utilize the other default gateway and firewall rules in my pfsense. Is there any reason you feel this isn't an option?

Thanks. Of course, let's say I am -obliged- to do this: the configuration software of the cameras assign to the devices only a 255.255.255.0 netmask.
In this way they are visible either from the machines in the A subnet or from the nodes in the B subnet, but not from all of them.
So the problem arises when I try to manage the cameras from a machine 'correctly' configured, i.e. with a 255.255.254.0 (belonging to the C=A+B net): if machine in the A subnet it sees only the A subnet, and dually the same for the B sub(half)net.Your router should be capable of routing between the them on the same hardware. For example I have a 10.10.10.0/24 and a 10.10.11.0/24 using the same network hardware and I routinely switch my machine between them when I need to utilize the other default gateway and firewall rules in my pfsense.

No, any particular reason. But having these constraints to the setup I was asking to myself and to the forum if pfsense could be a solution to it.
