I'm a developer and frequently have to run some tests. I work at a branch office and the servers are located at the head-office.
The branch office and the head-office are linked together by an hardware VPN box.
It has happened once or twice already that I connected to the live servers while I actually meant to connect to a test server in my office. Every time I noticed, but it is dangerous.
What I would like to do is block outgoing packets to the subnet of the Head-Office temporarily so that I can safely run my tests without the risk of mistakenly apply changes on production servers.
I could install an personal firewall for that and block the range, but I think it may be overkill? I am thinking there may be a lighter way, with the routes command maybe?
I'm working on Windows XP.
