Help Arma 2 OA server does not show on internet

ok so I tried to set up a server and had one working before the game spy shutdown. So I tried to reset it up for my friends and I Under steam.

this however proved to be quite challenging and I was unable to successfully set it up and after spending days scouring the forums on both steam and other ArmA related sites in the end gave up.

The problem is the server appears on my LAN network but not on internet and going via 'Remote' connection fail as well.

I have port forwarded all required ports TCP and UDP and gone through all possible options for this error but still I failed at setting the server up.

The server and pc specs are as follows:

Pc: Custom build Pc -

Processor Amd Athlon quad core (X4 750 K)

2 Hard drives one 1tb 1 2rb (server location)

8Gb of ram

64 bit Windows 8 OS
