Hi Till

Under ISPConfig DNS MAnager i have set the public IP at tab domain, and tab option i have also Public IP twise (at ns1 and ns2 too), and under records i set up both host www, one with private IP and other with the public IP.where i am wrong?

 

1. Your internal IP address looks suspiciously like a DHCP range. It should be fixed, and if it is fixed it shouldn't overlap with DHCP addresses. This isn't the cause of your current problem, but will probably cause your next one.

2. Your domain shows as registered to your DNS server - so thats a start.

3. NSLookup and Reverse Lookup both fail. This probably means your router is blocking incoming requests on ports 53 for DNS. It's clearly not communicating with the outside world.

Depending on your network setup, and I suspect by the sounds of things you have a single IP address being shared with your router you will need to open up the relevant ports - at least TCP ports 80 and 53 incoming - and ensure your router knows to forward those requests to your server. Optional will be if you want mail then 25, and if you want access to mail from outside your network port 110. ISPConfig is 81, FTP 21 (although routers might need 20 as well because FTP can be a bit weird), SSH 22.

There are so many different types of router I can't really tell you anymore, if it is a cheap DSL one, look for features called DMZ, Port Forwarding, Access & Gaming. On more expensive ones it will be part of a firewall setup, ACL or possibly called VIP or SIP.

 

port

hi
i work with router ADSL Speedtouch516, and all port is forward for my server wich have ip static 192.168.1.65
DNS port 53 both tcp and udp
ftp port 21
smtp port25
pop3 110
ispconfig port 81
http 80
I think my problem is on isp config
Under Management->Server->Settings->Server i have
Hostname ns1
Domain diasfast.ro
IP 192.168.1.65
IP list both IP private and public

Under DNS tab i have at default ns1 and ns2 same IP 89.122.18.58 (public)

on ISp Manager->sites->diasfast->basics i have
IP 192.168.1.65

At DNS MAnager->Domain i have
Doamin SOA diasfast.ro
Ip 89.122.18.58
At Option tab i put at nameserver1 and ns2 the public ip 89.122.18.58
and finally records tab i have
host www with both IP public and private
Note: the www.diasfast.ro i can see from my internal network, but from server and my internal network i can see diasfast.ro.
when i type traceroute diasfast.ro is no host
when i type traceroute www.diasfast.ro is found my host with my private ip.
where i am wrong?

 

Yep you're right. The network looks good, so probably a DNS setup problem. Sorry don't know anything about DNS.

 

ok

i fixit that settings.
In default nameserver and in nameserver 1 si 2 i have
ns1.diasfast.ro

at dns manager i have ip external 89.122.18.58
but still doesn't work
at ISP Manager at site diasfast.ro i have the internal IP 192.168.1.65
it's corect?

IT seems you did not define any nameservers for your domain. You must do that first in the web interface of your registrar.

 

sorry Falko

i have register my domain diasfast.ro at my registrar....www.rotld.ro
if you want to see...
you don't see my server because i will stop my server because is not working.
i will start this server in this moment, if you wanna check again...
thank's

 

The

Code:

dig ns diasfast.ro

command must show the nameservers regardless of if your server's running or not. This means you've probably not defined any nameservers for the domain at your registrar.
