How to use node command in wildcard/network virtual server?

Hi,

I need to change the destination of UDP packets in default wildcard virtual server, and I tried with the node command without success.

Namely, the iRules associated with the default wildcard virtual server 0.0.0.0:0 is:

when CLIENT_ACCEPTED {
  snat 150.236.43.70 5700
  node 150.236.43.80 5800
}

And UDP packets sent to the virtual server are not forwarded to the target node 150.236.43.80 at all.

However, if I remove the line containing the node command, UDP packets will then reach the targe node.

Can anyone tell me how to change the destination of UDP packets on the fly in such case? Thanks.
