I setup tomcat in my office, and it works fine. Then I went back home, and the tomcat looks still OK(i can browse my webpage made by jsp). However, after 2-3 hours, I cannot connect to the server from home. Then I went back to office, and find I can still connect to the server from other PCs in office and the tomcat works OK.
So the problem is: Tomcat works fine at the first 1-2 hours(for both intranet and from other isp), but I cannot connect to the server from other isp after several hours. Could anyone help me out? Thanks!!
