Is this correct? If you do not have permissions to change port forwarding in the router/firewall, then we can't use port forwarding. The Dynamic IP doesn't matter in this case anyway. You mention TeamViewer...do you need access to your computer remotely? I would talk to whomever setup the router first, but LogMeIn is web-based...no port forwarding needed. + 0 Votes If the port is blocked at the public switch/router seanferd 4 years ago you'll need to see whomever is in charge of that device in order that the proper ports be opened for the specific applications and protocols. If the switch is "dumb", or doesn't block anything, you'll need to check your local firewall to ensure the ports are open. The switch would need to properly send incoming traffic to your computer. If your computer only has a private IP on the LAN, you'll need to speak with whomever is in charge of that switch about configuring the connection. + 0 Votes Port Forwarding pinnakavamsi 4 years ago Hi, Thx for your reply My requirement is, i have Lab setup with cisco routers in my home. when i was using DSL Modem, i use to forward Telnet and SSH ports to access my rouetrs from my office. but now i am not using DSL modem. its a LAN connecion. it is like a shared internet. And my ISP is not providing any public IP for me. Every one in that LAN network will use same public IP. My question is.. is there any way to access my router over internet.. If it is not possible.. i will go for DSL connection..
