https://community.cisco.com/t5/network-security/cannot-ping-ftd-subinterfaces/m-p/4059702#M1068827 <P>Hi Guys,&nbsp;</P><P>We have some FTDs configured as DC firewalls, but the servers in those VLANs are not able to ping their gateway (FTD subinterfaces). Routing and policies work normally, but some systems need to be able to ping their gateway before their system setup actually will continue. Any ideas?</P><P>&nbsp;</P><P>Thanks!</P><P>Jacques</P><P>&nbsp;</P> Mon, 06 Apr 2020 08:36:56 GMT JACQUES DU PLESSIS 2020-04-06T08:36:56Z https://community.cisco.com/t5/network-security/cannot-ping-ftd-subinterfaces/m-p/4059702#M1068827 <P>Hi Guys,&nbsp;</P><P>We have some FTDs configured as DC firewalls, but the servers in those VLANs are not able to ping their gateway (FTD subinterfaces).
