Hi guys,
I have a funny situation.
We have a security PC that has it's own IP range 168.168.168.x and it has no access and needs no access to the internet.
What I have done is put another LAN card in and set up the new card with as per our company network, so we can remotely connect to the security PC on weekends and release doors, etc.
What I can't seem to work out is why can't I get these 2 LAN cards to work independently from each other and not let them see each other.
Suggestions ?
