Well, the /24 is denoting the subnet. That just means the dest_ip will be in the same subnet represented by the 254 IPs in the 192.168.2.x subnet.
I am also having the issue with the internet, however. I can access internet through the pineapple itself to download infusions, but the ICS is not working, and if it does, it is only for a few seconds. I don't know why, but I have had very little success with much of what the MKV has to offer thus far.
