title: tunneling to my private ip from outside network
body: <p>i want to telnet or ssh my pc (mac) at home from my office. How can i do this ? the problem i'm using router with private ip .Gateway is 192.168.1.1 and my pc is 192.168.1.100. I  think i should be able to do this when i forward the port in the router setting. But the problem i don't have public ip. My isp only give my dynamic ip (DHCP) , my router's external ip is just another private ip which is connected to another gateway (another level of LAN) which of course i don't have any access. so is it still possible to get access using telnet to my computer ? i read about the reverse ssh but that only works if i have to setup the connection first from my pc. In my case now there's no body near my pc. i just turn it on so i can hopefully access it.</p>
  
  <p>Is there any workaround ? or it's just impossible to do that ?</p>
  
  <p>Thanks</p>
