Hi Pablo, Please apply the next patch to your nf-next tree, which introduces a new feature in ipset: - The patch adds the new "bitmask" parameter to the hash:ip, hash:ip,port and hash:net,net types. While the existing "netmask" parameter accepts only valid netmask values, "bitmask" takes any arbitrary IP address and makes possible to mask out arbitrary bits. Patch is from Vishwanath Pai.
