How can I limit Internet Access to only a single workstation? – Wayne Small

Thursday, May 3rd, 2001

You can reconfigure Proxy Server to only allow a specific workstation to use the internet by changing the LAT to only include the IP of that specified workstation.

To do this, firstly give the chosen workstation a fixed IP address, and exclude it from the DHCP scope. Then go into the Proxy MMC, drill down to the Web Proxy and go to properties. Select the “Local Address Table” button, then type in the workstations IP address for the From and To sections and add it to the LAT. Remove all other entries in the LAT, give the workstation the fixed IP address mentioned above, and restart proxy.

You may also want to change the permissions to remove all access control, therefore making the workstations IP address the only limit to users surfing the web.

How does Dynamic DNS work?

Tuesday, May 1st, 2001

Dynamic DNS is where the router is always allocated a dynamic IP address by the ISP. The router then contains software which works with specific third party organisations, who control their DNS records. The router monitors the existing IP address given by the ISP and advises the Dynamic DNS provider of any changes to the IP. The Dynamic DNS provider then publishes any change in the users IP via it’s DNS servers. The customer must have their SOA for their domain name registered with these Dynamic DNS providers, or alternately have a subdomain registered with them.

Most dynamic DNS providers offer an option for hosting yourcompany.com for a fee, or yourcompany.DNS2Go.com for free. If you register your domain name through a register that will let you manage your own info (instead of the ISP or web host) then you can

direct yourcompany.com and your MX records to yourcompany.dns2go.com,and get the functionality and retain the ability to make changes.
