교재 내용대로 vm 생성했는데 22 connection time out으로 접속이 불가합니다.

external은 192.168.200.0/24 인 라우터에 묶여있고 (nat로 외부 통신 가능)

internal은 192.168.210./24 대역 라우터에 묶여있고 (외부 통신 불가)

neutron-ex는 192.168.200.0/24인 라우터 (external과 다름) 로 묶여 있는 상태 입니다.

 

통신이 안되는 이유가 있을까요?

 

vm -> 10.10.10.253, 192.168.200.131

kolla-internal 10.10.10.0/24

kolla-exsubnet 192.168.200.0/24

 

kolla-security

IPv4 tcp to 0.0.0.0/0 허용

IPv4 icmp from 0.0.0.0/0 허용

IPv4 tcp from 0.0.0.0/0 허용

default

IPv6 to ::/0 허용

IPv4 to 0.0.0.0/0 허용

IPv4 from default 허용

IPv6 from default 허용

 

접근은 192.168.200.0/24 대역에서 진행했습니다 (external router)

확인 부탁드립니다

 

+ ssh 접근은 안되고 콘솔은 되는 상황이라 혹시 패스워드를 미리 지정해서 인스톨 하는 방식도 있을까요? 감사합니다
