Redirect Port

Hello Everybody,

 

 

I have a case over here that i need to redirect the port that hits my VIP meaning

 

 

I have already a Service running on port 80 and all the requests that i receive are going through this port while the back end servers have the port 7778 running on.

 

 

So all i need is when i receive any request on port 7778 to be redirected to port 80

 

 

Http://10.10.10.1:7778/index.htm > http://10.10.10.1/index.htm

 

 

What i thought of is this but it didnt work i might need your help folks :

 

 

when HTTP_REQUEST {

 

if {[TCP::client_port] != "80"}{

 

HTTP::redirect "http://10.10.10.1[HTTP::uri]"

 

}

 

}

 

 

Thnx in advance

    can you try this? 

    [root@ve1023:Active] config  b virtual list
virtual bar {
   destination 172.28.19.79:any
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
virtual bar80 {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        HTTP::redirect "http://[getfield [HTTP::host] ":" 1][HTTP::uri]"
}
}

[root@ve1023:Active] config  curl -I http://172.28.19.79:8080/test

    i tried this rule before but always shows :

     

     

    The page isn't redirecting properly

     

     

    and the curl -I http://10.10.10.1:7778/index.htm doesnt come with output

     

     

    i need to find the port it self in the Host like HTTP::host contains "7778" or ":" but it doesnt catch it

     

     

    any idea ?

    can you post your virtual server configuration?

    i just noticed you are using TCP::client_port. it shoud be TCP::local_port.

    when browsing http://10.10.10.1:7778/, it won't hit your virtual server since it is listening on port 80. you have to create another wildcard port virtual server something like the one i posted above or use only one virtual server like the following. 

    [root@ve1023:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:any
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b pool foo list
bpool foo {
   members 200.200.200.101:80 {}
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        if {[TCP::local_port] != 80}{
                HTTP::redirect "http://[getfield [HTTP::host] ":" 1][HTTP::uri]"
        }
}
}
