Problem connecting to https from the local lan to WAN on same network

Hi all,

I have a alixboard with m0n0wall running on it.
All is working well as firewall but I want to make a connection from whitin my company to our outlook web access.

We used to check our E-mail sometimes from someone elses computer not logging off and loggin on with our own username and password. So we use the Outlook Web Acces.

Https://webserveripaddress/exchange   Username and password and we can view our mail.
No we have installed this m0n0wall firewall and we want to do the same.

But we are getting a page diplaying the page cannot be found.
No for me this is not a big issue. I type in the IP address of the server and view it local thrue the LAN side


But others don't know this.
What do I need to change so the https connection can work again from within the LAN side.

Lan -> any rule is set.
on the WAN side

HTTPS port 443 is set to go to the localipaddress

Hope we can find the solution.

Best regards,


A.k.a. Wim

i'm not sure about how to do it with your firewall but it sounds like you need to do something called DNS doctoring

I would simply add a DNS name fr the mail server that everyone should use via the LAN side.

where mail1 is set up in the DNS as the mail server IP
I hope this helps !

Hi all,

Since I have never done this before where do I need to add a dns record?
on the server? Or do I need to make an MX record in the dns of the website?
Or somewhere else?

Please advice some more

Since this is a LAN issue, it should be done on the local DNS server ( usually your  DC ) via the DNS applet in the Admin programs

I hope this helps !

Okay, I found on my server DNS setting.

I have forward lookup zones. and reverse lookup zones.
Where should I add what?

in the forward zone. I can see my own domain.


I guess I have to create something in here but what?
