One website blocked

Mon Apr 15, 2019 6:58 pm

Hello everyone, I have a problem accessing one website.
It is
It is the only one that I cannot reach.

When I ping the website I get the following ip but no reply, also when i try this from the router there is no reply.
The local network is Netmask
DHCP - 240
NAT is enabled

The internet side (isp) is Netmask Gateway

The most firewall rules are basic rules and some NAT rules to allow traffic from outside.
All other https sites are working perfectly and also http sites.

I tried to monitor what is happening with the website traffic but I did not really succeed.
How can I see why this website is unreachable?

First of all, you are right - they don't respond to a ping. However that proves absolutely nothing since some network admins drop pings as some people consider it a security hole.

If it really is on your end, please post your config, so we can see what you have.

In order to export your config, follow these instructions that forum user anav posted to another thread.
To get a copy of the config you simply go to the left hand menu 'new terminal' icon in winbox and type in
/export hide-sensitive file=yourconfig (any name you wish)
Then to go the left hand menu 'files' icon and you will see the file there saved.
Right click and download to your desktop.
I use notepad ++ to open up config files.

Then simply copy and paste into the thread here. The only thing you should do is ensure that your ISP WAN address and ISP gateway address are not being shown.
Check ISP client setting and perhaps IP route settings for that.

To make the code appear elegant use the text bar above where bold is and highlight the code and then apply the icon that is a black square with white square brackets inside it.
RB750Gr3, RB750r2, CRS326-24G-2S (in SwitchOS), CSS326-24G-2S, CSS106-5G-1S, RB260GS
Not sure if I beat them in submission, or they beat me into submission

The internet side (isp) is Netmask Gateway
Netmask is wrong. With /8, is part of local subnet, which it definitely isn't. Correct mask is most likely /24.
People who quote full posts should be spanked with ethernet cable. Some exceptions for multi-topic threads may apply.

Changed the Netmask to /24 and that fixed the problem.
Thanks for the help
