Wildcard VS does not forward traffic on assigned VLAN

Hi there, I need some help from the community. 🙂 I can't get a wildcard virtual server to match/forward traffic. I've been fighting with this for a few days now. Maybe I'm missing something sim...

I'm testing with TCP. I did packet captures on the F5 with tcpdump and see SYN's sent from server on self-ip VLAN but no packets match the wildcard virtial server per LTM stats.

 

My goal is to match all traffic (TCP, UDP) sent from servers (F5 set as gateway in inline mode) and forward to a specific gateway (pool) that is different from gateway configured in LTM.

 

I thought I could use a Performance L4 virtual server with a "alternate gateway pool" but maybe I need to use a Forwarding IP virtual server as described here: https://support.f5.com/csp/article/K7595. Maybe in conjunction with separate route-domain for alternate default route?
