Using firewall and port forwarding rules only we can access the VM services from the public network also from the VMs using the Public IPs. For you telnet from outside network success but from failed from VM to VM using public IP. Seems hair pin NAT got failed ...
Please capture the packets on the telnet server VM to see whether telnet packets are reaching or not ? Which version of cloudstack Is it ?

My Cloud system run 2 VMs in advance zone with private IP is 10.1.1.20 and 10.1.1.21 and VM NAT IP is 192.168.50.160 and 192.168.50.165. From outside network, I can ping and telnet port 80 to both VMs with public IPs. But from VM 10.1.1.21, I can't telnet to other VM with its public IP. For details: >From VM1: 10.1.1.20 and 192.168.50.160. ping 192.168.50.165 and ping 10.1.1.21 success telnet 10.1.1.21 80 success telnet 192.168.50.165 80 fail >From VM2: 10.1.1.21 and 192.168.50.165 ping 192.168.50.160 and ping 10.1.1.20 success telnet 10.1.1.20 success telnet 192.168.50.160 80 fail And I can't telnet another ports with public IP. Can you suggest some solutions for me to telnet VM from another VM via public IP. Thank !
