How to use a specific IP to access specific sites by?

My Company registered in certain services on the Web and are relying on the开发者_运维技巧 company's IP to use these services, Director asked me to allow some staff to enter these sites from outside the company, after authorized staff enter to comany's site.

How could they use the company's IP to allow them to browse services sites?

Do I need to use a method such as proxy sites like youtube proxy? or there is another way?How do I do this in asp.net?

Thanks in advance.

You need to create a VPN.

You could also create a proxy.

If you are trying to use the external services from the IP address of a company server you will have to direct the query from your company IP to the external services on behalf of the employee. The employee would be connecting directly to your company server.

Proxy server may be one way of doing this. You can also re-write your code to forward queries from the company server to the external services on behalf of your user which is what I suggested above. Depends on how deep you would have to go in your code to determine which is better/easier.
