NimbostratusIn nPath configuration, BIG-IP does not send ICMP reply to the L3 switch.
MVPHi TKC,
in a typical nPath configurtation your server dont use F5 as Def-GW. It should be your router. F5 should only see and balance ingress traffic...
Any specific reasons to use F5 as Def-GW on your servers?
Cheers, Kai
NimbostratusHi Kai,
Because the server needs to verify the source IP.
I understand that if I change the G/W of the server to L3 and configure Automap, I need the X-forward-for function to check the source IP.
However, the G/W of the server was configured as L4 because the end customer was not able to use the X-forwared-for feature.
I searched on the forum and I think it can be solved with forwarding virtual server.
Is it possible to solve it with the configuration below?
