Allow website access

RouterOS Beginner Basics
1

Hi,

I’ve created a local intranet website on an IIS7 server. It’s all setup and running, I’ve checked it from the server and it’s accessible.

However, any computer on the network cannot access it. Any idea why? Is it a firewall or port issue?

It’s on port 93 if that helps.

Could you please telnet to your server IP (from any computer other then the server running the website) on port 93 and check if you get a response?

Besides that…a lot of questions:

  • why port 93?
  • IIS7…why? Think that version is ancient!?
  • What Windows version are you running?
  • Does your Windows firewall allow incoming calls?
  • Why are you posting this on a MikroTik forum?

  • why port 93? - I’m happy to switch it to 80, not an issue.
  • IIS7…why? Think that version is ancient!? - Because it’s what they have at the place i’ve just started
  • What Windows version are you running? - Running Windows 10 on my computer and windows server 2008 on the webserver (i’ll be upgrading it).
  • Does your Windows firewall allow incoming calls? - I’ll have to check this
  • Why are you posting this on a MikroTik forum? - Because I didn’t know if it was the mikrotik RB850G router that is blocking it from all the other computers on the network.

Well, it requires users to add :93 in the URL.

  • IIS7…why? Think that version is ancient!? - Because it’s what they have at the place i’ve just started

My advice, don’t make this a public facing webserver

  • What Windows version are you running? - Running Windows 10 on my computer and windows server 2008 on the webserver (i’ll be upgrading it).

That is a very good idea!

  • Does your Windows firewall allow incoming calls? - I’ll have to check this

Please do!

  • Why are you posting this on a MikroTik forum? - Because I didn’t know if it was the mikrotik RB850G router that is blocking it from all the other computers on the network.

Do you have the MikroTik firewall inbetween the LAN connected computers and the server?

    Well, it requires users to add :93 in the URL. - I’ve added it in the URL, doesnt work. I’ve even put everything in the dns so it uses a dns name rather than an ip address, and it resolves on the iis server but not on other computers in the network.

    My advice, don’t make this a public facing webserver - I don’t want to, I want it as a local intranet website just for the computers on the network
  • What Windows version are you running? - Running Windows 10 on my computer and windows server 2008 on the webserver (i’ll be upgrading it).
    That is a very good idea!
  • Does your Windows firewall allow incoming calls? - I’ll have to check this
    Please do! - it does allow incoming calls to the iis server
  • Why are you posting this on a MikroTik forum? - Because I didn’t know if it was the mikrotik RB850G router that is blocking it from all the other computers on the network.
    Do you have the MikroTik firewall inbetween the LAN connected computers and the server? - it is.

Configure the firewall for allowing access to the webserver.

(1) Are your trying to access the server from PCs on the same lan as the server
Yes - then simply use the lanip of the server to gain entry

(2) Are your trying to access the server from PCs from a different LAN/subnet than what the server resides on?
Yes - then you may need a firewall rule to allow such traffic depending upon current firewall rules in place.

(3) Are you trying to access the server from PCs behind the router BUT WISH TO USE YOUR PUBLIC WANIP to access the server.
Yes - You need to setup Hairpin NAT on the router.

Yes we definitely need to see the config of the router to be of any assistance…
