F5 Default Gateway Request

Hey guys,   So I have half of my pool of servers pointing to the F5 as the default gateway and the other half pointing to the firewall. Is there any way I can see what ones are pointing to the F5,...

My .02 Feel free to correct me.

 

IIRC --

 

If your servers are pointing to your F5's Self IP's as their gateway, your VIP will not have a SNAT setup; it will be configured as "None." If you have "Auto Map" configured, your servers will use one of the Self IP's that you have setup for that VLAN segment. If you have "NONE" setup for the VIP and the Servers do not have the F5 as their gateway, traffic will fail.

 

Also if you do a tcpdump for a VIP IP, you will see the IP's that are talking to the F5.
