Hello.
My question is about pinging a public IP address from an ESXi shell.
The context is the following:
- a Cisco ISR4331,
- a NIM E-Series NCE (UCSE) module inside the ISR4331,
- a VMware ESXi host installed on the UCSE.
Some configuration from the ISR4331:
interface GigabitEthernet0/0/1.60
encapsulation dot1Q 60 native
ip address 192.168.3.1 255.255.255.0
!
interface ucse0/1/0
ip unnumbered GigabitEthernet0/0/1.60
no negotiation auto
switchport mode access
!
interface ucse0/1/1
no ip address
shutdown
no negotiation auto
switchport mode access
!
ucse subslot 0/1
imc access-port shared-lom console
imc ip address 192.168.3.61 255.255.255.0 default-gateway 192.168.3.1
!
ip route 192.168.3.61 255.255.255.255 ucse0/1/0
ip route 192.168.3.62 255.255.255.255 ucse0/1/0
Pinging the CIMC interface (192.168.3.61) and the ESXi vmk0 interface (192.168.3.62) from the ISR4331 works:
isr4331(config)# do ping 192.168.3.61
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.3.61, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/2/5 ms
isr4331# ping 192.168.3.62
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.3.62, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Some commands output from the ESXi shell:
esxi_shell# esxcli network ip interface ipv4 get
Name IPv4 Address IPv4 Netmask IPv4 Broadcast Address Type DHCP DNS

I can ping the gateway (192.168.3.1) from the ESXi shell.
But I cannot ping any external address (like for instance Google's IP address 8.8.8.8).
Can you please help me find out what's wrong in my configuration?
Thank you and best regards.
