Problems with NAT? Can't access internet from inside the network?
I was intrigued with this problem for a few days now. I'm stuck on what could be the issue. The problem is that I can ping my router, G0/0 and G0/1, to the internet. However, since the switch and my PC, I can not ping Internet. I'm sure that everything is configured correctly, but here is my setup for the switch and the router:

Well, I totally forgot the keyword "log" and NAT:
Cisco IOS NAT support ACLs with a keyword "log"?
A. When you configure Cisco IOS NAT translation dynamic NAT, an ACL is used to identify the packages that can be translated. The current NAT architecture does not support the ACL with a keyword "log".

If your problem is not the mask with joker, but the command "log"...

Problems with nested cflayout and IE 7-9, inside the cfwindow
I have a page that uses cflayout to display data. Links in the page triggers a cfwindow containing also a cflayout tag. It works perfectly in all other browsers, including IE 10, but not IE 9 and below. It produces no error, it just does not display anything at all. Window with nothing in it. Server-side is CF9.01.
Any ideas? Thank you very much!
Test your tag cfwindow with single output. Continue to add things until it starts to behave badly. Then you know what is the cause of the problem.

I can't access internet wirelessly from my laptop because I installed a new printer which is now connected to my router, is - it related somehow?
Hello
1. what happens when you use a wired connection?
2. how many devices are connected to the router?
This can happen if you connect that a specific number of device to the router, and when it exceeds the limit. You can consult the router's manual or contact the manufacturer of the router to check if all the parameters must be changed to connect several devices.
Hope this information is useful.

Adobe community, I have 2 quick questions on Adobe Creative Cloud membership. I am considering the Adobe Creative Cloud 'Plan of the student' for 2 children currently in high school. (1) is the license for 1 or can it covers 2 users? (2) can they access it from PC or MacBook this year? Thanks for your help.
each single-user license, it's just that, for a single user and can not (legally) be shared between two different users.
programs of CC can be installed on pc or mac. each user can install on an unlimited number of computers, but can only connect to, at most, two computers at a time. These 2 computers can be 2 pcs, 2 macs, or one of each.

Prioritize network connections
OK, here's the situation.
I have a regular ethernet connection that provides me with a network and the internet.
I have also a tablet PC which I attach to my PC so I can use it as a controller. (Not that it is important, but it's for a DAW/Midi controller)My problem is that whenever I place my tablet, PC starts by ignoring my normal connection and taking the internet from my Tablet (even when it is not connected to the internet). As a result, my internet is de-energized once I tie it, if I'm not as under the wifi on my tablet.
My question is, how could I give priority to my network connections, (without turning off the strap attached, as it took), so that it uses the internet from my main network connection?
