Cisco Container Platform 2.2.2 - non-windows machine can't access internet

vMarkJavier

I'm using the Cisco Container Platform lab to deploy Cisco collaboration (CUCM/CUC/IM&P/CUBE-csr1000v) but the appliances can't access the internet. I've tried installing an Ubuntu server and it can't access the internet as well so my conclusion is that non-windows machines can't traverse the internet. does anyone have a solution for this?

You can try to connect the remote server using http or https. ICMP is not always available to all network.

I've tried ping cisco.com from the csr1000v host and it is reachable:
csr1000v#ping cisco.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 72.163.4.185, timeout is 2 seconds:

Have you configured gateway & DNS for your VMs? The gateway should be 10.10.20.254, and DNS is 10.10.20.100.

As you know, we are also using CentOS/Ubuntu in our lab and both of them can access Internet.

yes. I've also tried it on the CSR and this is what I get.

 

csr1000v#show ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override, p - overrides from PfR

Gateway of last resort is 10.10.20.254 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 10.10.20.254
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.10.20.0/24 is directly connected, GigabitEthernet1
L 10.10.20.19/32 is directly connected, GigabitEthernet1
csr1000v#ping 8.8.8.8 rep 5

I've tested it again... now, this is really weird. what do you think?
