the problem is as follows:
when I gateway IP is router IP I have no problems with Internet access, but if gateway IP is DNS IP I have no internet access at all.
Does anybody know where the problem is?
Thank you in advance
let me explain what I need. I'm going to install ISA on my DC, unfortunately have no separate machine for that. All PCs have external IP addresses at the moment, so they can see router. But when I put all the PCs into the privete internal network, I'll have to set DC-ISA server IP as gateway IP.
Or am I wrong?
