Oops! I was thinking DHCP. I didn't change the clients' DNS setup,
assuming what worked with the linksys router would work with the
dedicated firewall. Since ping is failing, DNS doesn't seem to be the
immediate cause of my problems. All the clients are configured to use
128.171.3.13, a DNS server here at UH.
