Thanks thesugarat, will try that out this weekend, but it sure sound like it will solve my problem. Googled some on SharingNetworkNumberStart looks like I can set it but on newer versions on osx it is ignored by the os.

I have similar problems, followed the instructions in the video and I can connect to http://172.16.42.1:1471/ from my mac(mountain lion). But then I turn on the internet sharing I can not connect to the pineapple anymore. Then I tried with # set sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkNumberStart 172.16.42.0 and then I turn on the sharing still the same problem. I get the following from ipconfig(en1 is the thunderbolt connection): en1: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=b<RXCSUM,TXCSUM,VLAN_HWTAGGING> ether a8:20:66:27:d1:10 inet6 fe80::aa20:66ff:fe27:d110%en1 prefixlen 64 scopeid 0x6 media: autoselect (100baseTX <full-duplex,flow-control>) status: active bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether ac:de:48:31:be:c1 inet 172.16.42.1 netmask 0xffffff00 broadcast 172.16.42.255 Configuration: priority 0 hellotime 0 fwddelay 0 maxage 0 ipfilter disabled flags 0x2 member: en1 flags=3<LEARNING,DISCOVER> port 6 priority 0 path cost 0 Any ideas what is wrong?
