Ok thank you.Also how much $ does CompTIA cost?
1. Dynamic DNS is basically an automatic updating DNS. If you understand the basics behind DNS than all Dynamic DNS does is usually a small application that sits on the network and as soon as it detects an IP change it publishes that new information immediately to the Dynamic DNS server so it can be on the internet as soon as possible. This way it reduces errors when trying to reach destinations that change IP addresses.
2. VPN passthrough is just like port forwarding. If you have a VPN device behind a router and you dont enable passthrough the valid IPSec packets could be dropped. Passthrough will enable these packets to come through without being bothered. I dont see much of a use for this for a personal PC, for business or a company it will be more relevant.
If you want to learn more about networks, CompTIA offers a Network+ course. Its a great start into networking.
ok sorry for the late post
The exams have to be administered at a testing facility. Pearson VUE is a company that will handle that this Link is for ordering the test voucher I believe Network+ is $185 USD. Also on their page you can find out where the testing centers are located.
