라우터의 Shorewall은 가상 게스트에 대한 apt-get 업데이트를 계속 차단합니다.

이중 IP가 있습니다.LXC세 명의 사용자를 위해 구성된 권한 없는 여러 컨테이너가 있는 서버입니다. 각 사용자는 자체 브리지( lxcbr0, lxcbr1및 ) 를 갖습니다 lxcbr2. 효율성을 위해 호스트는 apt-cacher-ng이를 사용하도록 구성됩니다.cat /etc/apt/apt.conf.d/31apt-cacher-ng

Acquire::http { Proxy "http://217.8.191.52:3142"; };

네트워크 설정

Shorewall이 시작되면 호스트는 apt-get update다음과 같은 오류를 생성합니다.

Err http://security.ubuntu.com trusty-security/universe amd64 Packages
  500  Connection failure: Network is unreachable
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/restricted/binary-amd64/Packages  500  Connection failure: Connection refused

내가 삭제할 때/etc/apt/apt.conf.d/31apt-cacher-ng 또는안벽( sudo shorewall clear본체의) 청소가 apt-get update작동합니다.

rulesinclude 에서 많은 규칙을 시도했지만 ACCEPT all all아무것도 변경되지 않았습니다. 내 Shorewall 구성은 다음과 같습니다.

상호 작용:

net eth1 detect routefilter,dhcp,routeback,tcpflags,blacklist,nosmurfs,dhcp
- loopback detect ignore
lxc lxcbr0 detect bridge,routeback,dhcp
lxc lxcbr1 detect bridge,routeback,dhcp
lxc lxcbr2 detect bridge,routeback,dhcp

영역:

fw  firewall
lxc ip
net ip

사향:

eth1 10.0.0.0/16

정책:

$FW all ACCEPT - - -
lxc all ACCEPT - - -
net all DROP - - -

규칙(모든 호스트 이름이 있음 /etc/hosts):

SECTION NEW
DNAT all lxc:apaczek:22 tcp 1300
DNAT all lxc:hostA:22 tcp 1223
DNAT all lxc:hostB:22 tcp 1221
DNAT all lxc:hostC:22 tcp 1222
SSH(ACCEPT) all $FW
Ping(ACCEPT) all $FW
DNAT all lxc:hostA:22 tcp 22 - 217.8.191.53
ACCEPT lxc $FW tcp 3142 #To allow access to apt-cacher-ng
