I have not had a lot of luck using Trend Micro with the SR520 routers. The current problem I am having is when someone accesses a website the SR520 locks up and I cant talk to the internet I can talk to it locally only. After a long time of troubleshooting I found out that it is with the Trend Micro integration. I have removed it and the problem completely stopped. I have removed and replaced the configuration but I am missing something. My best guess is that the website is permitted but something on the website is not and I certainly could be wrong. I noticed that blog websites cause this problem alot. Anything on blogspot.com. Tmz.com does this too. I have included the running configuration as well as the "sho version". Thanks in advance!
