Join Sean Colins for an in-depth discussion in this video Troubleshooting server-side firewall issues, part of Mac OS X Server 10.6 Snow Leopard: DNS and Network Services.
The way we configured the firewall in the last movie left your client in the…awkward position of being unable to access the server remotely.…That's okay because right now you're experiencing what happens if you set up a…firewall rule and it blocks your access.…It really isn't possible to get past it, is it?…It's rather annoying.…Well, this is why we advised you to have a monitor, keyboard and mouse…attached to the server, because this is where you're going to actually really, really need it.…On the server, we want you to open up Server Admin.…When you open up Server Admin, you're going to go to the Server, go to Firewall,…and under Settings, in Address Groups, what we're going to do is we're going to…create a new rule that has the IP address of our client machine.…
We're going to allow it full access. Okay?…So we're going to click the Plus button, we're going to give it a name that…makes sense to us, and we're going to put in exactly its IP address, and we're using 12.20.…If you're using a different IP address, feel free to put it in here now, and click OK.…
