Hello EEs,

Greetings,

How the URL Work for external users regards to RWW & OWA?

Pls explain me since I have never configure… ..how domain name can be accessible from outside world?
If my domain name (mydomainname.com) is registered with www.netsol.com  & the internal domain name will be like mydomainname.local,

External users will access RWW by typing https:// mydomainname.com /remote, but what all I need to configure in my account in www.netsol.com with my domain name, take it granted that I have one Pool of IP which I have assigned as per below:-
•       Cisco Router S 0/1/0 = 100.100.100.230
•      Free Public IP I have = 100.100.100.231 – 235

Kindly explain with the example in case of RWW & OWA traffic separately meaning RWW(with the url like http://remote.mydomainname.com ) traffic will use 100.100.100.231 & SMTP (with the url like http://mail.mydomainname.co  ) will use 100.100.100.232

Kindly explain with the example or any use full text / video link will really be appreciated.

Many thanks,

DXB

Hi,
You should have dns manager(domain name server) or something like that from your domain register.
Then like your AD make a  A record and give your external ip number to your homepage.
for your mail you need to create MX record like thet
in domain manager page select mx record and give you server name for your mail server equal to
100.100.100.232
and just a record for your remote server equal to 100.....

Hello Asr,


Thanks for your reply,

Do you mean i have to set A record for the url binding with the desired IP i want?

Like if i want to add a url http://remote.mydomainname.com with the IP of RWW server in the A record section.

Kindly explain with the example,

best regards,

Here is an example,
your remote server has ip 192.168.2.12 local and name myserver.remote.com
you get 2 external ip addres from your net provider(100.100.100.1 and 100.100.100.2). then in your domain name server under your domain
name you should add entry choose a record and
myserver ip number has 100.100.100.1
and one for your mail server (mymailserver.remote.com)it sould be a mx record
mymailserver has ip number 100.100.100.2.
look at the attach file something like that

Thanks Asr for your fantastic reply with example,

What all I Created the following in this order:-

1. NS record = mydomainname.com/remote (What is Refresh, Retry Interval)

2. A record = EBS-SEC.mydomainname.com with the IP 100.100.100.1 (For Remote Access of my server)

3. MX Record = EBS-MSG.mydomainname.com with the Mail Traffic IP i.e. 100.100.100.2 (What is Preference?)

Kindly advice am i going right?

Awaiting for your earlier reply.

Many thanks,

Hi,
Yes it correct. What you mean with what is preference.
If you f.x have a exchange and localy have web mail under http://ebs_msg.mydomain.com/exchange
After your extern mx record, it's not just local.

Thanks Asr for your reply,

I mean to ask What is Refresh, Retry Interval  & Preference? what are the use of these parameters?

We will be installing internally Exchange Server but not Web Server,

I understand that MX records will be external not internal,

Where will i have to mention PTR records & how they will be configured with my IP / my domain name (coz i have

come to know some domain must check reverse PTR records)

Kindly let me know with the example as you did in past,

Many thanks,

DXB

Hi,
Ok. The refresh interval is the number of seconds at which the secondary domain name
server will try to synchronize its records with the primary domain name server. and retry is
Used to determine how often other DNS servers that load and host the zone are to retry a request for update of the zone each time that the refresh interval occurs.
But may be you can't see this when you use other name server (or dns register firm).
about the exchange and mail.
if you don't want web server then you do not use the first register in our example (i mean 100.100.100.1)  but for mail you need that.
when you install exchange with smtp then you can send mail withou any problem dosen't matter you register your domain or you have an external mx record. But you don't recive any mail because you don't have register your domain and mx record to get the mail. when i send mail to you first look at the domain then mx record then give the mail to your server and your server to you.
So for mail (dosen't matter you use owa or not) you need that. and ocourse you need also mx record internal too.
about ptr:
PTR records resolve IP addresses into hostnames and back like that
look at this link here is very goog ex.
https://hosting.intermedia.net/support/kb/default.asp?id=1317
for creating ptr look at this link

I hope you can use it otherwise ask and i try.
