Пробую разобраться в ASA под GNS3настроил три интерфейса
interface Ethernet0/0
nameif outside
security-level 0
ip address 10.10.1.1 255.255.255.0
!
interface Ethernet0/1
nameif DMZ
security-level 100
ip address 10.20.1.1 255.255.255.0
!
interface Ethernet0/2
nameif inside
security-level 100
ip address 10.30.1.1 255.255.255.0
Настроил NAT
nat (DMZ) 1 10.20.1.0 255.255.255.0
nat (inside) 1 10.30.1.0 255.255.255.0
global (outside) 1 interface
Навесил acl
access-list outside_in extended permit icmp any any echo-reply
access-group outside_in in interface outside
На интерфейсы подключил виртуальные машинки с ubuntu: inhost, outhost и dmzhost
ping c inhost и dmzhost до оuthost ходит, и в sh xla есть записи - NAT работает
теперь хотел пробросить порты 22 на inhost:22 и 222 на dmzhost:22
добавляю следующее
static (inside,outside) tcp 10.10.1.1 ssh 10.30.1.3 ssh netmask 255.255.255.255
static (DMZ,outside) tcp 10.10.1.1 222 10.20.1.3 ssh netmask 255.255.255.255
и
access-list outside_in extended permit tcp any host 10.10.1.1 eq ssh
access-list outside_in extended permit tcp any host 10.10.1.1 eq 222
по теории должно работать, а нет
пробую диагностировать

Не пойму почему по ACCESS-LIST DROP?
