Global cache itach IR2WIFI or Flex IP now broken with smartthings

hi, i have been using the global cache itach flex for like 7 years with smartthings… today i switched cable modems, and changed the ip [in hex format] in my smart apps that use it… now nothing works.

i used iTest to make sure the IPs were right and the commands still worked fine, and they do… it looks like smartthings isnt sending the signal after the cable modem change over [has a built in router].

the ips changed from like 192.168.0.x to 10.0.0.x … does this have something to do with it do you think?

can anyone help?
