MTU is really a matter

Long time ago, I lower the MTU of my router to solve a networking issue (see my previous blog entry). However, it is not the end of story.
Recently, I have changed my job. My new company provides Citrix Presentation Server for employees to work at home via remote desktop.
Then, at home, I tried to connect to Citrix server and run remote desktop. I can login but the link is very unstable. It disconnected every 10 to 20 seconds.
After some investigation, I found it is the MTU problem again. The problem is fully explained at the following site:

I should change the MTU of my desktop at home to match the router. Finally, it works!
