Joe,

If it's helpful, I ran tcpdump on the director and each of the real servers
while attempting to connect to the VIP using telnet.  Only the director
reported any packets:

[root@www1]# tcpdump -n -i eth0 port http or telnet or icmp or arp
17:07:13.226377 < 24.162.230.236.64523 > 209.116.71.36.telnet: S
4149809018:4149809018(0) win 32768 <mss 1460,wscale 0,nop> (DF)
(...many more rows that look the same as above...)

I tried listening to both eth0 and lo on the real servers, but nothing
seemed to come in:

[root@www3]# tcpdump -n -i eth0 port http or telnet or icmp or arp
(...nada...)

[root@www3]# tcpdump -n -i lo port http or telnet or icmp or arp
(...still nada...)
