Hello everyone, this is my first post here.
And when i am at work, i first thought VNC would have been able to connect to computers outside of a lan but i have noticed it has not worked.

So what i would like to do is be able to connect from my work computer to my home computer, so an external connection, if anyone could help me with this, i would be greatly appreciative.
Please help me, and thank you =]

For an internet-side connection you need more than the VNC program itself: the home router and any firewalls must be told to pass incoming traffic to the PC, and the home public IP may change. is trying to reach a home machine from work; suggestion (a direct-cable approach) only helps for local, physical links and will not solve an across-the-Internet connection.

Practical checklist to get VNC working remotely: assign the home PC a fixed LAN address (or a DHCP reservation); on the home router set port forwarding from the router to that LAN address for VNC (default 5900, and 5800 if using the VNC web server); make sure the host firewall allows the VNC server; verify the VNC server is listening by connecting from another machine on the same LAN before testing externally.

If your home public IP changes, use a dynamic DNS service so you can reach yourname.dyndns.org instead of a shifting number. Test from a genuinely external network (mobile data or a friend) because some routers do not support "NAT loopback" and tests from inside the same LAN using the public IP can fail. If an external test fails, common culprits are an incorrect LAN IP in the forwarding rule, an active host firewall, ISP blocking of inbound ports, or outbound restrictions at work.

Security and alternatives: do not expose VNC without encryption. Prefer a VPN or an SSH tunnel, or use a remote-access tool with built-in NAT traversal (reverse connections) if you cannot change the router. Also check your workplace policy before attempting remote access. Typical troubleshooting steps are: test local VNC first, recheck the router forwarding and target IP, confirm the public IP (or DynDNS name), then test from outside while watching router/firewall logs for rejected traffic.

I assume one of them is a laptop?

I'm thinking crossover cable....

Nope
I'm at work on a workstation and want to connect to my PC at home, it's not a labtop...
