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 simple?

Setup is HA pair / BIG-IP 13.1.0.3 Build 0.0.5 Point Release 3

A little background.

I created this wildcard vs in response to following requirements:

1) Send tcp,udp syslog traffic to new pool (lets call it syslog_pool) in VLAN100

2) Preserve source-ip header for all traffic sent to new pool (No SNAT)

In order to preserve source-ip I set the floating self-ip (172.16.0.6) in VLAN100 as the default gateway for servers in the syslog_pool (instead of usual gateway 172.16.0.1). This is to prevent an asymmetric route with snat automap disabled.

However the default-route on the F5 pair is not appropriate for traffic sourced from these servers destined for external networks.

I tried to solve the default-route problem by sending all traffic sourced from this VLAN back to the correct gateway (pool vlan100_net_gateway [172.16.0.1] in VLAN100) as follows (IP's and VLAN ID's obfuscated):

ltm virtual syslog_ip_route_0 {
    destination 0.0.0.0:any
    mask 255.255.255.255
    pool vlan100_net_gateway
    profiles {
        ip_route_fastl4 { }
    }
    source 0.0.0.0/0
    translate-address disabled
    translate-port disabled
    vlans {
        VLAN100
    }
    vlans-enabled
    vs-index 1540
}

ltm profile fastl4 ip_route_fastl4 {
    app-service none
    defaults-from fastL4
    idle-timeout 300
    loose-initialization enabled
    reset-on-timeout disabled
}

ltm virtual-address 0.0.0.0 {
    address any
    arp disabled
    icmp-echo disabled
    mask 255.255.255.255
    traffic-group traffic-group-1
}

net self 172.16.0.6 {
    address 172.16.0.6/24
    allow-service all
    floating enabled
    traffic-group traffic-group-1
    unit 1
    vlan VLAN100
}

Problem: zero traffic matches this wildcard vs. Stats on the virtual server, the virtual address, and vlan100_net_gateway pool are all zeros.

I can ping the floating-ip (default gateway) from the servers.

I can access any VIP on the F5's (listening on all VLANs) from the servers via floating-ip as default gateway.

I see only SYN's for traffic sent to external networks when watching on the F5's with tcpdump.

I even tried moving VLAN, Self-IPs, Pool and VIP to brand new route domain. Same issue. 0 Traffic.

Any ideas?

Thanks!
