iRule not executing

Is a HTTP profile assigned to the VS?

if you run curl on bigip, is it executed?

 curl -I http://virtual_server_ip/

if you run curl on bigip, is it executed?

 curl -I http://virtual_server_ip/

Perhaps some additional logging?

when HTTP_REQUEST { 
    log local0. "incoming URI = [HTTP::uri]"
    if { [HTTP::uri] equals "/" } {
        log local0. "catch and redirect for /" 
        HTTP::redirect "http://crm.murrob.com:5555/murrayroberts" 
    } 
}

Strange .. it only appends triple 5 and not 5555

it seems okay here.

 test

[root@ve11a:Active:In Sync] config  curl -I http://172.28.24.10:5555/
HTTP/1.0 302 Found
Location: http://crm.murrob.com:5555/murrayroberts
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

 config

[root@ve11a:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  if { [HTTP::uri] equals "/" } {
    HTTP::redirect "http://crm.murrob.com:5555/murrayroberts"
  }
}

both curl and tmsh list outputs shows the four digit port number - however still no redirect

if curl shows redirection correctly but it still does not work, you may have to try tcpdump on bigip and/or http analyzer tool on client to see where the wrong is.

HttpFox

for tcpdump, you may try this.

 tcpdump -nni 0.0:nnnp -s0 -w /var/tmp/output.pcap host x.x.x.x -v
x.x.x.x is client ip
