>Description:
There is regression in ipfw table adding, in compare with, for example, 9.0-RELEASE.
Adding some hostname in a ipfw table leading in appearance of record '::/0 0' instead of correct IPv4 address. See below ("how to repeat the problem").
After this record appeared in ipfw table it passing ALL traffic, even all IPv4 addresses.
