I set up a LVS with one director and two realserver. Using DR method, I successed to set up a http service, However, it failed to connect the realserver through https services

the Structure is as below:

Prot LocalAddress:Port Scheduler Flags
 -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  10.0.58.136:443 rr
 -> 10.0.58.232:443              Route   1      0          2
TCP  10.0.58.136:80 rr
 -> 10.0.58.230:80               Route   1      1          8
 -> 10.0.58.232:80               Route   1      0          7


and after numbers of accesses of HTTPS, information has showed below:


IP Virtual Server version 1.0.10 (size=65536)
Prot LocalAddress:Port Conns InPkts OutPkts InBytes OutBytes
 -> RemoteAddress:Port
TCP 10.0.58.136:443 15 76 0 4330 0 -> 10.0.58.232:443 15 76 0 4330 0 TCP 10.0.58.136:80 236 1868 0 333760 0 -> 10.0.58.230:80 45 566 0 127198 0 -> 10.0.58.232:80 191 1302 0 206562 0


Althrough I can't accesses the https service, but the realserver showed the trace as below

tcpdump -n -i any port 443
tcpdump: listening on any

The web farm did not set any firewall , Can you help me to solve the problem?

Thank You Very Much~1
