DNS Trick to MAP Retail Game Servers
Got an error message but I got the feeling I didn't do it right.Well I originally posted this on NGU, but I think its better suited here. I have configured 2 VPS servers with a DNS server software. They are configured for a list of games I will try to update.
I am not responsible for anything that happens VIA use of these servers. I do ask you consider donating to your right. It helps me with server costs, and shows your appreciation for my work. To use my servers is quite simple. Just set your primary and secondary DNS to one of the following IP addresses and use.
United Kingdom: 18.104.22.168
United States: 22.214.171.124
Modern Warfare 2
Call of duty: World at War (Should, IDK whats with 1 address mapping to a game and auth server)
Call Of Duty: Black Ops
Medal of Honour
James Bond 007: Blood Stone
WWE All Stars
Battlefield: Bad Company 2
Have Fun online, and don’t forget who helped you while doing so..
