send to pool-member by port-range

Question

I have an problem to get it to work right.&nbsp;
&nbsp;I have made an VL om port any, with an default pool.&nbsp;
&nbsp;some ports have to go to one server ande some ports have to go to the other server. I have made an iroule (paste belowe) but it only works evry 2. time. I am not sure the iroule have any effekt, it might only use the LB bye the VL ???&nbsp;
&nbsp;when CLIENT_ACCEPTED {
&nbsp;set srv_port [TCP::local_port]
&nbsp;if { $srv_port &gt;= 6740 and $srv_port &lt;= 6749 } {
&nbsp;pool mpapp-pool member 10.10.66.22 $srv_port
&nbsp;log local0. "Client sent to $srv_port"
&nbsp;} elseif { $srv_port &gt;= 6830 and $srv_port &lt;= 6839 } {
&nbsp;pool mpapp-pool member 10.10.66.21 $srv_port
&nbsp;log local0. "Client sent to $srv_port"
&nbsp;} elseif { $srv_port &gt;= 6860 and $srv_port &lt;= 6869 } {
&nbsp;pool mpapp-pool member 10.10.66.22 $srv_port
&nbsp;log local0. "Client sent to $srv_port"
&nbsp;} elseif { $srv_port &gt;= 6880 and $srv_port &lt;= 6889 } {
&nbsp;pool mpapp-pool member 10.10.66.21 $srv_port
&nbsp;log local0. "Client sent to $srv_port"
&nbsp;} elseif { $srv_port &gt;= 7000 and $srv_port &lt;= 7009 } {
&nbsp;pool mpapp-pool member 10.10.66.22 $srv_port
&nbsp;log local0. "Client sent to $srv_port"
&nbsp;} else {
&nbsp;log local0. "no match on port $srv_port"
&nbsp;}
&nbsp;}&nbsp;

The rule looks fine.  What does the client see on the request which fails?  What logging do you see for a failure?&nbsp;

I can see every 2. connection are LB to the other server (the wrong one), it seems for me that it is working with the default pool and not the iRoule.&nbsp;
&nbsp;I have tryed to make an other iRoule (paste below), this one is working with no default pool, but the iroule might be written in an other way ..... : (the pools in this iroule have only one of the servers..)&nbsp;

That makes sense.  A request which doesn't match any condition in the rule would be sent to the default pool of the VIP, if one is configured.  If there isn't a default pool, the request will be dropped.&nbsp;
