IP Forwarding Config for single server

If you don't want to load balance then why don't you NAT the IP addresses instead of creating virtual addresses?

 

 

Option-1: Use an IP address that is not routed to the LTM and NAT it with the node IP on your firewall itself

 

Option-1: NAT on LTM (you should have a forwarding VIP configured to forward the SMTP traffic)

 

 

Sample forwarding VIP to forward all traffic:

 

 

virtual ForwardingVIP {

 

ip forward

 

destination any:any

 

mask 0.0.0.0

 

profiles fastL4{}

 

}

 

 

still if you wanted to get it through the LTM, then create a VS, Pool and the node as pool member like any traditional VS, and since you do not want the traffic to return, then do not attach any SNAT configuration to it.
