In nPath configuration, BIG-IP does not send ICMP reply to the L3 switch.
Hi All, 1) The Client sends an ICMP request to the 20.20.20.10 node IP destination. 2) Since the G/W of the Node is self-IP of BIG-IP, ICMP reply is sent to BIG-IP via the L3 switch. 3) BIG-...
> you should change your configuration little bit , use one of two scenarios :
Change the default gateway for "20.20.20.1" instead of using Bigip self-ip as a gateway , and configure ( SNAT automap or SNAT pool ). by this scenario , ICMP traffic should go through L3 swith without forward it to Big-ip All of this with respect to your routes.
Configure a fast layer 4 virtual server on your Big-ip and do not assign tcp profile to it , allow all protocols. After creating it , go to virtual address and configure "echo-reply = disabled " not "always" like below :
in this scenario , ICMP traffic should go through Bigip to server 20.20.20.10 and return back to F5 big-ip " its gateway"
> you only need to adjust your traffic flow , I recommend to do the first scenatio , using SNAT is very useful , so try it.
