      Is pfsense supporting VLSM addresing? Because I'm trying to set one interface A with 192.168.0.0/23 and another interface B with 192.168.2.0/22 and it's say's this configuration overlaps the first subnet in interface A. But with vlsm this is wright. Does the order of interfaces have a meaning because interface B is first and then is interface A. Or Pfsense only accepts one type of subneting?

        Yes, it does support variable length subnet masks. However, you have overlapping subnets. That 192.168.2.0 /22 is in fact 192.168.0.0 /22 because the mask erases the .2 in the 3rd byte of the address. The next network up that supports /22 is 192.168.4.0.

        I haven't lost my mind. It's around here...somewhere...

            Indeed i've miss-understand vlsm. And it's wright what you ar saying because vlsm works ordering from bigger subnets to smallest subnets. That's why i got the error.
            Thanks, any way.. I have to check how to reordenate my subnets... thanks in advance...
