We had purchased a SonicWall NSA2400 to replace our ISA server 2006 and once we got in we found the SonicWall was not capable of handling host header redirection that ISA server was so we just put the SonicWall in front of our ISA server.  This works fine except we are seeing some dropped connections such as websites responding they are too busy and some not loading correctly although some web sites load completely and sometimes the web sites we are having trouble with do.  Connections Crome the outside seem to be fine although they are really slow (remote web workplace, outlook web access, etc.). 15 seconds or longer.  Any help would be greatly appreciated.

We have DSL for Internet access and are using a zyxell DSL modem for access that sits in front of the SonicWall.  Thanks again for any help.

Disable any content filtering. Also there is a setting under users about holding packets while waiting for user authentication, set that to not hold packets.

Hi rcblevins,

What security licensing do you have on the SonicWALL and what of it is enabled and configured?

How is the overall throughput? Is it isolated to just web browsing?

If throughput, in general, is fluctuating or poor try change the MTU in the SonicWALL as set forth in this article. It explains how to get the correct MTU value: http://www.experts-exchange.com/A_12615.html

>We have DSL for Internet access

Try changing the MTU packet size to 1492.

That seems to have worked on the MTU size. Thanks for your help!
