ASA5515-X (9.12.4) tricky route issue

ronald.su

Level 1

we have an ASA and it only connected inside interface. (only 1 cable connected inside interface, no outside interface)

 

and the inside interface ip is 192.168.0.4/24

our internal network have 192.168.0.0/24 and 192.168.59.0/24 and 10.5.0.0/16

we added a default route to our 3 layer core switch(192.168.0.5), the core switch have all network route table.

then , we can ping the devices in 10.5.0.0/16. not packets loss.

but when we can't ping devices in 192.168.59.0/24  (it's seems the default route not work?)

 

and here is the most tricky part:

add route : route inside 192.168.0.0 255.255.0.0 192.168.0.5 got around 50% ping loss

add route: route inside 192.168.59.0 255.255.255.0 192.168.0.5 no packet loss
