I install fresh ROS 3.6 from Netinstall on x86 PC, install Dude package, install demo (level 1) license key. At next step, I change (in /ip services) webbox port from 80 to 8080 and 443 to 8443. At next, I connect from Dude client to Dude server on installed ROS and enable web access for port 80 and 443. At next step, when I try to connect to Dude server from IE, I got “Page cannot be dispayed” 
Can anybody say to me, where a problem?
can you connect to the dude on localhost at the server?
did you configure the allowed addresses for connection to the dude server?
No, I cannot connect to port 80 from localserver
[admin@Dude] > system telnet 127.0.0.1 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
Welcome back!
In Dude config, access to web interface allowed from 0.0.0.0/0 network. Also, I don’t have any firewall rules on ROS where Dude living.
May be this problem based on license restrictions of level 1?
you may want to configure the allowed networks setting. If I remember I had to do this before I could connect to the server, even when using localhost. Also, ensure that telnet is not being denied on the server. Not knowing your OS in this case I can’t recommend more specific settings to check.
I'm in much the same boat as ArtKZ.
I have RouterOS v3.9 for x86 running on a PC (demo licence) on the same network as my 'work' PC. I can access RouterOS via Winbox and Dude with a Windows client (3.0beta8) on my 'work PC. But web access doesn't work.
In Dude settings I've allowed remote and web access for the whole network (Dude PC=10.3.2.106. Windows PC=10.3.2.101. Allowed networks=10.3.2.0/24). The Dude default setting for web access is Port 80, but of course 10.3.2.106:80 just brings up the RouterOS logon page. https://10.3.2.106:443 brings up the "IE cannot display the webpage" message.
I've tried changing the port number but IE cannot display it whatever I try.
This is my IP services list, but if there's a way to add a new service/port it's hidden from me and I don't want to use any of these ports for something else.
[admin@felicity] /ip> service print
Flags: X - disabled, I - invalid

5 X api 8728 0.0.0.0/0
6 winbox 8291 0.0.0.0/0
[admin@felicity] /ip>
So what's the secret of web access to the Dude?
You will need to add the 127.0.0.x/x to this in order to connect locally. If you want to connect from a remote machine, you need to add its’ address range as well, i.e., 168.0.0.1/16, 192.245.0.0/x, etc. You should then be able to connect.
Write ‘/dude’ after the ip adress/hostname in browser
Doh!
Thanks sytex.
Lesson = “Always try the obvious first.”
How can I access my dude server using blackberry web browser. x.x.x.x/dude or x.x.x.x:81 do not work. HTTP error 504 Gateway time out.
