I have trouble with adding in my list Latvian local addresses.
When I try to add address like 80.250.52.0/22 (from http://www.nic.lv/local.net ) going out error : address ranges may not overlap
My MT version 2.9.39
In earlier version alsoo was this problem

please check you address list, that error message means that you already have inserted addresses that are in the lsit and that will be added when you add that network.

Thanks janisk

I lookup my list and undrestend the problem - this IP wal aready defined in other address range
