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
# NAME PORT ADDRESS CERTIFICATE
0 telnet 23 0.0.0.0/0
1 ftp 21 0.0.0.0/0
2 www 80 0.0.0.0/0
3 ssh 22 0.0.0.0/0
4 www-ssl 443 0.0.0.0/0 none
5 X api 8728 0.0.0.0/0
6 winbox 8291 0.0.0.0/0
So what's the secret of web access to the Dude?
