Firewall slowing download speed

intodesi · 06-15-2007, 10:30 PM

Hello, just joined the site, had a question about some issues im having, googled this site, and was hoping i could find an answer, maybe a solution.

Im not going to display operating system, computer build information, because i know the problem I am having has nothing to do with that, because the rpoblem doesnt exists with those details only

I have a 10mbit up/1mbit down connection. I am running a small home network containing the following.

Mortola Cable Modem
SB5101 Cable Modem
SURFboard® Cable Modem

http://broadband.motorola.com/catalo...?ProductID=399

Linksys Cable/DSL Router
http://www.linksys.com/servlet/Satel...=4094131284B01

3com officeconnect internet firewall 25
http://www.3com.com/products/en_US/d...sku=3C16770-US

Linksys 24 port switch

PC1
MY pc

PC2
Significant Others PC

My issue seem's to be with the firewall, doing a speedtest i am only seeing 3.5 mbit down, while still seeing the 1 mbit up, i narrowed it down to the firewall, because without it I can clock the downstream to 9 or so mbit. upsteam stays the same.

Any thoughts or will i need to provide more info?

Thanks

Travis

I suspect that the processor in your firewall appliance isn't up to the task of providing full bandwidth. You will probably have to upgrade that component to something a bit more "robust" to solve this problem.
