Hi Guys,
I use FMC1600-K9, version：6.6.4, and FTD: FPR2130-NGFW-K9
My FTD(10.131.175.35) can NOT ping the direct connection interface IP(10.131.175.34) which is my gateway
but it is pingable after I do "clear arp" on FTD, it could be pingable for about 2 mins. after about 2 mins, the it will be unreachable/unpingable, which mean the session will be end,
I checked the cabling, and ARP, interface protocol, it worked fine.
The router(10.131.175.37) to ping FTD, and GW(10.131.175.34) both worked fine,
Guys, May I know if you have any idea ?
Thank you very much!
