[IuliiNet] port forwarding su mikrotik

[Luca Postregna]

non funziona ancora, questa la situazione sul mikrotik:

[admin at mikrotik] > ip address print
Flags: X - disabled, I - invalid, D - dynamic
 #   ADDRESS            NETWORK         INTERFACE


 0   ;;; default configuration
     192.168.88.1/24    192.168.88.0    ether2-master-local


 1 D 192.168.0.25/24    192.168.0.0     ether1-gateway


[admin at mikrotik] > ip firewall nat print
Flags: X - disabled, I - invalid, D - dynamic
 0   ;;; default configuration
     chain=srcnat action=masquerade to-addresses=0.0.0.0
out-interface=ether1-gateway

 1   chain=dstnat action=dst-nat to-addresses=192.168.88.20 to-ports=81
protocol=tcp in-interface=ether1-gateway dst-port=81
[admin at mikrotik] > ip firewall filter print
Flags: X - disabled, I - invalid, D - dynamic
 0   ;;; default configuration
     chain=input action=accept protocol=icmp

 1   ;;; default configuration
     chain=input action=accept connection-state=established

 2   ;;; default configuration
     chain=input action=accept connection-state=related

 3   ;;; default configuration
     chain=forward action=accept connection-state=established

 4   ;;; default configuration
     chain=forward action=accept connection-state=related

 5   chain=forward action=accept connection-state=new

 6   chain=input action=accept protocol=tcp dst-port=81


questo è l'nmap da 192.168.0.0/24:

> nmap -sT 192.168.0.25

Starting Nmap 6.00 ( http://nmap.org ) at 2014-06-05 12:21 CEST
Nmap scan report for MikroTik (192.168.0.25)
Host is up (0.016s latency).
Not shown: 995 closed ports
PORT     STATE    SERVICE
22/tcp   open     ssh
53/tcp   open     domain
80/tcp   open     http
81/tcp   filtered hosts2-ns
2000/tcp open     cisco-sccp
MAC Address: D4:CA:6D:E2:95:B9 (Routerboard.com)

Nmap done: 1 IP address (1 host up) scanned in 1.31 seconds


se da 192.168.88.0/24 faccio un nmap sull'ip del servizio, ottengo:

> nmap -sT 192.168.88.20

Starting Nmap 6.00 ( http://nmap.org ) at 2014-06-05 12:30 CEST
Nmap scan report for 192.168.88.20
Host is up (0.044s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
23/tcp   open  telnet
81/tcp   open  hosts2-ns
2000/tcp open  cisco-sccp
5000/tcp open  upnp
MAC Address: 00:4A:20:A9:4B:2E (Unknown)

Nmap done: 1 IP address (1 host up) scanned in 0.60 seconds

dove sbaglio?
