IP address filtering rule does not work

Hi All,

I wanted to create a rule to block all IP addresses except one IP address. So, I gave this rule:

when CLIENT_ACCEPTED {
 if {! [IP::addr [IP::client_addr] equals x.x.x.x] } {
 
}
}

When I try accessing the web page associated with this VS, I am not able to access it from anywhere (that is, am not able to access it even from x.x.x.x which is supposed to have access). Can someone help me with this?

Thanks and Regards,

Geethanjali

    can you put some log command to see what is going on?

    e.g. 

    [root@ve10:Active] config  b virtual bar list
bvirtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
}
[root@ve10:Active] config  b pool foo list
pool foo {
   members 200.200.200.101:80 {}
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
   if { ! [IP::addr [IP::client_addr] equals 192.168.206.57] } {
      log local0. "Reject [IP::client_addr]:[TCP::client_port] -> [IP::local_addr]:[TCP::local_port]"
      reject
   }
}
when SERVER_CONNECTED {
   log local0. "Allow [IP::client_addr]:[TCP::client_port] -> [clientside {IP::local_addr}]:[clientside {TCP::local_port}] -> [IP::remote_addr]:[TCP::remote_port]"
}
}

[root@ve10:Active] config  cat /var/log/ltm
