thanks, I have made a test successfully in A subnet using VS-TUN,
while when I try to make the test in TWO subnets, some strange thing
happened,
DIP=192.168.2.3
VIP=172.16.2.41
CIP=172.16.2.63
RIP=192.168.2.1
the director act as router at the same time,
I can ping from RIP to CIP or from CIP to RIP, and
I also can telnet from CIP to RIP,while when I telnet
from CIP to VIP, it failed, in RIP machine, the command
'netstat -n' shows something as follow:
tcp 0 0 172.16.2.41:23 172.16.2.63:3821 SYN_RECV
and in DIP machine, the command 'ipvsadm -ln' shows:
[root@faint /root]# ipvsadm -ln
IP Virtual Server version 0.9.8 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 172.16.2.41:23 wlc
-> 192.168.2.1:23 Tunnel 1 0
1
thanks for any comments
ttao.
