Hi ,
after applying dnat on interface ping, to that interface from outside is
not working.
following is my config.
vpp# show interface address
GigabitEthernet0/14/0 (up):
L2 bridge bd-id 1 idx 2 shg 0
local0 (dn):
loop1 (up):
L2 bridge bd-id 1 idx 2 shg 0 bvi
L3 192.168.10.24/24
vpp# show nat44 static mappings
NAT44 static mappings:
tcp local 192.168.100.253:443 external 192.168.10.24:443 vrf 0
udp local 192.168.100.253:3799 external 192.168.10.24:3799 vrf 0
identity mapping udp 192.168.10.24:53053 vrf 0
tcp local 192.168.100.253:443 external loop1:443 vrf -1
udp local 192.168.100.253:3799 external loop1:3799 vrf -1
udp local 0.0.0.0:53053 external loop1:53053 vrf -1
now from remote machine with ip of 192.168.10.2(some linux machine) when i
ping to 192.168.10.24 (VPP)
there is no response and vpp trace shows following.
