Hi,
I think I have done what I can to try and get the following to work.
All traffic on port 80 on the Director to be sent to two Real Servers.
I have tried nat, ip tunneling and direct with no success.
The Director server has ip forwarding on.
[root@lb300 lvs]# ./clvs
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.20.20.16:80 rr
-> 10.20.20.14:80 Masq 1 0 0
-> 10.20.20.15:80 Masq 1 0 0

Connecting to 10.20.20.16:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 86 [text/html]
On the Director I can fetch a file from one of the real servers using the address 10.20.20.16
` When I try it from another machine and access 10.20.20.16 externally I used tcpdump to observe that the Director gets the request and doesn't seem to forward it on.
