Amit, why are the two VLANs in a VLAN group? Your configuration doesn't seem to warrant it nor does it meet the features requirements.

i agree with Steve. i do not think you need vlan group. 
&nbsp;  
&nbsp; can you remove vlan group and configure ip forwarding virtual server?

1) Virtual server :- 10.192.77.1&nbsp;
  pool :- &nbsp;
 node :- 10.192.77.80 : 59573&nbsp;
              10.192.77.81: 59573&nbsp;
2) Virtual Server:-10.192.77.1&nbsp;
 pool:-&nbsp;
   node:-  10.192.77.80:59572&nbsp;
                 10.192.77.81:59572&nbsp;
3)Virtual Server:-10.192.77.1&nbsp;

   node:-  10.192.77.80:135&nbsp;
                 10.192.77.81:135&nbsp;
I am not able to ping these host Ip from external network.&nbsp;
NITASS ,I remove the VLan group and i am still facing this issue and know i also not able to ping my F5 VLan ip 10.192.77.65 .&nbsp;
 &nbsp;
Please suggest that i can do loadbalanacing  as wel as i  can do ping and telnet to these host ip.  &nbsp;
 &nbsp;
Thanks &amp; Regards&nbsp;

kridsana · Answer

can you tcpdump packet on internal ? to see packet is send but not receive or else

nitass · Answer

I remove the VLan group and i am still facing this issue and know i also not able to ping my F5 VLan ip 10.192.77.65 .i do not think you can ping internal selfip (10.192.77.65) from external vlan.

&nbsp;  
&nbsp; I am not able to ping these host Ip from external network.to ping host ip (10.192.77.80, 10.192.77.81), i understand you need ip forwarding virtual server.
