DSM-G600, DNS-3xx and NSA-220 Hack Forum

It is possible that the firewall at the user end - if he is behind a NAT firewall/router - can prevent the connection, have someone test it using a dial up connection (or PM me the details and I test from here).

It's probably going to take a little more than "turning off his firewall".

I'm not talking about a software firewall here - I was very specific when I said behind a NAT firewall/router.  If he is using a NAT firewall/router, as most people do nowadays to share a broadband internet connection, that NAT firewall/router needs to know how to deal with an incoming ftp data connection, some of them don't, and quite frankly, if they don't then disabling the firewall won't change anything - which is why I suggested trying it from a dial up connection.

Does he get a public ip address on the PC?

One that does not start with 192.168, 172.16 or 10.?

another question,

ik open port 21 in my modem/router for the ip adress of my router.
ik check it with pfportchecker and it is open.
the next day when i check again, its closed....?
any idea?

does this have anything to do with the problem?

his port 21 is closed. so maybe he has to open that one first with
portforwarding?

i shall explain the things i have done, cause i think it easier for u to understand.

i open the website of my router and have access to make changes.

i opened a virtual server and then made a rule to open port 21. then saved.

when i then open ftportchecker it gives me the ip adress op the ROUTER

and says its open.  see image 1.

the ip adress off the DNS DRIVE is 192.168.1.3.
this i got on the screen when i installed it and mapped a drive (Z) .


maybe important. The dns automatically shuts off after 10 minutes.

when i shutdown the computer and restart later, ftportchecker says the gate is closed. and the rule
is gone in the right screen under "applied rules". Its only in the section "available rules".
when i then put it in the "applied rules" section and save, the port is open again.

I hope the pictures help.

But all what i did above, is portforwarding port 21 in the ip adress of the Router. Maybe it should be
in teh dns drive ip???  but ftportchecker only show the ip of the router.

ok

seems i have 3 ip adresses

router : 192.168.1.2 static

dns 313 : 192.168.1.3

external ip : 83.101.61.207  i get to see this one on www.whatismyip.com
due to forum help we got further, but not quite there, =-)
i forwarded port 21 in my router for the dns ip  .....1.3
the user tried accessing the maps on the dns through the following address:

  ftp://hans@83.101.61.207

so "hans" is the username i granted access and he had to use the external ip adress.
RESULT: he is asked to type his username and pasword and then gets access to the maps
on my dns. PROBLEM: he can see them but cant open them. see picture.

when he tries to open it says : "page not available"...
