SPI Firewall

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.

Hard reset the router to factory defaults and start over. You may have
inadvertent rules that affect only those two machines, or the upgrade
might have corrupted your settings.
