I am running a Linksys WRT54GS router (firmware v4.72.1) with the SPI firewall turned on. I have four computers all running Windows XP that could access the Internet until just recently. Now 2 have access and 2 don't. The only change that I can think of is a firmware update to the router about a month ago. I have checked the obvious such as encryption codes, MAC numbers and IP addresses. I found out when I turn off the SPI firewall all the machines can access the Internet. When I turn the firewall back on only to have access. Any suggestions or comments will be helpful.
