Hi,

        Ok that's what I thought, and I think that I've done that but I can't 
telnet 
into the cluster (aka telnet into the director). I've got some tcpdump 
output, I hope it'll be useful:

From the director to the real server:

12:32:10.046938 172.16.1.2 > 172.16.1.3: icmp: redirect 172.16.1.1 to host 
172.16.1.1 [tos 0xc0]
12:32:10.074104 172.16.1.2 > 172.16.1.3: icmp: time exceeded in-transit [tos 
0xc0]
12:32:12.126151 arp who-has 172.16.1.2 tell 172.16.1.1
12:32:12.126472 arp reply 172.16.1.2 is-at 0:a0:c9:aa:2:fc
12:32:12.134636 arp who-has 172.16.1.3 tell 172.16.1.2
12:32:12.134853 arp reply 172.16.1.3 is-at 0:a0:c9:c9:8:31

From the director to the client:

12:30:10.365644 172.16.1.3.1041 > 172.16.1.1.23: S 86960724:86960724(0) win 
8192 <mss 1460> (DF)
12:30:10.365838 172.16.1.3.1041 > 172.16.1.1.23: S 86960724:86960724(0) win 
8192 <mss 1460> (DF)
12:30:10.365869 172.16.1.3.1041 > 172.16.1.1.23: S 86960724:86960724(0) win 
8192 <mss 1460> (DF)
12:30:10.366061 172.16.1.3.1041 > 172.16.1.1.23: S 86960724:86960724(0) win 
8192 <mss 1460> (DF)
12:30:10.366082 172.16.1.3.1041 > 172.16.1.1.23: S 86960724:86960724(0) win 
8192 <mss 1460> (DF)

Where will it be getting the IP 172.16.1.23 from? I can't remember ever 
entering it in.

Any suggestions?
