If the latter is the case how can I get my IP address or redirect the switch to my computer. I don't know much about DSL switches. Thanks!
Hi there,
I work for an ISP and sell ADSL's all the time.
While a full tutorial of how to set up your ADSL to run services such as VNC would be beyond the scope of this forum, there are a couple of areas you need to look at in order to connect to your computer running VNC from school.
1. The type of IP assignment from your ISP:
This will usually be a dynamic IP address, meaning that each time you reconnect to the ISP your 'external' IP address will be assigned from a pool of addresses (and will usually be different). Other account types would either be a single static IP address, so each time you reconnect you'll get the same IP number, and there are business/premium ADSL accounts that can allocate a range of public IP addresses (a routed block), meaning all devices on the LAN will have world-routable IP addresses (rather than private ones assigned by your ADSL modem/switch).
2. The configuration of your ADSL modem/router/switch:
This really depends on whether your modem's set up for a routed block of IP addresses or if your ADSL modem/switch is performing network address translation (NAT). I'm fairly certain your modem/switch is running NAT, so you'll need to look at a couple of workarounds. One is to set up your ADSL modem/router with port forwarding to allow the VNC protocol to be passed to a designated computer on the (internal) network. Another method, if you only have a single computer, would be to set up the modem/router to perform 'DHCP spoofing' which simply passes the single external IP straight through the switch to the computer.
Also, if you're using a firewall you'll need to make sure the necessary VNC network ports are opened up.
Again, you'll need to find out more about the IP settings for your ADSL service and read the documentation that came with your modem in order to set it up for port forwarding or DHCP spoofing.
Importantly, you'll need to get up-to-speed with general networking/IP terms if you're unsure what all this means.
