Is it possible to somehow display a maintenance notice to users of our WISP of upcoming maintenance outages, ect? It would be neat to display when they try to go to a web page or to just display every few hours. Maybe some type of a pass through web page. Not sure if it's even possible. I am very new to Mikrotik and still learning. Whenever we have to do some upgrades to our system we get a lot of calls about being down. This maintenance notice might help with that. I may be wishing for something that's not even possible. Any ideas or help would be appreciated.
Thanks
Re: Display Maintenance Message To Users
Yes this is possible !
Simply create a NAT rule that redirects http port 80 requests to your local/external proxy service which deny all requests and redirect to local web server page which shows the MAINTENANCE PAGE.
Now create a NETWATCH rule that can keep monitoring any reliable HOST on internet , probably your ISP DNS or GOOGLE DNS , if the link is down, then DOWN script should be triggered which enables the NAT Rule, so in case of any link down all users will be routed to maintenance page, and when the link gets UP, the up script will disable the NAT rule, and internet will start work at user end normally.
Some Examples:
First the NAT rule which actually redirects port 80 requests to internet/external proxy server.
[Make sure the comments remains same in all rules of nat / netwatch, otherwise script will not works,
Now ENABLE web proxy which will deny requests of all users port 80 requests and redirect them to local web server page showing the reason why internet is not working.
Now the Netwatch script which will keep monitoring the internet, and act accordingly
Result:
You can achieve this task with more sophistication and controlled method by using scripts to do various functions like frequency, check multiple hosts instead of single, act according to latency load results, email function, and much much more,

Re: Display Maintenance Message To Users
Awesome. Thanks for the reply. I will see what I can do with your scripts. I am new to Mikrotik and its scripting but with your post I think I can get it working.
Re: Display Maintenance Message To Users
This script is not working/ip proxy
set always-from-cache=no cache-administrator=webmaster cache-hit-dscp=4 cache-on-disk=yes enabled=yes max-cache-size=unlimited max-client-connections=600 \
max-fresh-time=3d max-server-connections=600 parent-proxy=0.0.0.0 parent-proxy-port=0 port=8080 serialize-connections=no src-address=0.0.0.0/ip proxy access</pre>
add action=deny disabled=no dst-port="" redirect-to=10.0.0.1/netdown.html
70% of script around is not working , it will be helpully if you check twice your script before posting them

Re: Display Maintenance Message To Users
Try this, there were some spacing problems./ip proxy
set always-from-cache=no cache-administrator=webmaster cache-hit-dscp=4 cache-on-disk=yes enabled=yes max-cache-size=unlimited max-client-connections=600 \
max-fresh-time=3d max-server-connections=600 parent-proxy=0.0.0.0 parent-proxy-port=0 port=8080 serialize-connections=no src-address=0.0.0.0/ip proxy access</pre>
add action=deny disabled=no dst-port="" redirect-to=10.0.0.1/netdown.html
/ip proxy set always-from-cache=no cache-administrator=webmaster cache-hit-dscp=4 cache-on-disk=yes enabled=yes max-cache-size=unlimited max-client-connections=600 max-fresh-time=3d max-server-connections=600 parent-proxy=0.0.0.0 parent-proxy-port=0 port=8080 serialize-connections=no src-address=0.0.0.0
/ip proxy access add action=deny disabled=no dst-port="" redirect-to=10.0.0.1/netdown.html
You will have to make a file on the mikrotik called netdown.html which will be called anytime the rule is enacted.

Re: Display Maintenance Message To Users
All method described are not working in case of fail.
If your network is down there are five(or more really) possibility:
1) The client request http://www.google.com page which already are on your DNS, AND YOUR CLIENT USE YOUR DNS, and correctly the system display the maintenance page.
2) The client request http://www.google.com page which already are on CLIENT DNS cache, and correctly the system display the maintenance page.
3) The client request http://www.google.com page, but client use external DNS like 8.8.8.8.
The DNS are unable to resolve the address and the client browser display "server not found" instead a maintenance page.
4) The client request http://www.google.com, but you do not have http://www.google.com cached on your DNS.
The DNS are unable to resolve the address and the client browser display "server not found" instead a maintenance page.
5) The client request http://www.google.com, the client use YOUR DNS, and you have the DNS configurable to answer all the time with fixed IP for not found DNS (like OpenDNS), and in this way the client display correctly the maintenance page.
*******************
For aacable only:
Hint: STOP using third party source for check....
Think if one time Google stop service for maintenance on 8.8.8.8
Have you one idea about how much system are considered faulty / reboot / wrong routing.....
*******************
Have you tried this? "make a file on the mikrotik called netdown.html"
You can not put file inside mikrotik routerboard and make it visible directly. except when using hotspot or customization package (if you buy one stock of 1000 Level3 devices)
"redirect-to=10.0.0.1/netdown.html" are referred to another web server, not routerboard itself.

rextended,
Quite right on that one, when I do these I use the hotspot as a mini web server. The hotspot is set to allow all pages/addresses as permitted without being logged in (causing it to serve files). I put my unavailable page there which eliminates the need for a web server that is usually unavailable when the network is being worked on anyway. I forgot to note that since most providers I work with are redundantly served from multiple sites the up-times are 4-5 9's on those networks which also means I haven't done configuration of a page like this in quite some time. This is also likely not the best way to do it but it works when I need it and it is completely independent.

I posted just a very basic and simple solution that one can use to get get a very basic idea on hwo it can be achieved , But in a real network, more intelligent method should be used like multiple host check up , not only google dns.
I mentioned that earlier.

and if there is really a maintenance problem , it will not grab that page from that server to post on user browser

Re: Display Maintenance Message To Users
there you go.
somebody improved on the script for showing a maintenance page posted here viewtopic.php?p=822430
and posted at this site https://buy.guru
it works perfectly and works flawlessly, attaching the direct link to script here.
but as written do remember to create a second folder and populate it, else it wont work!

Sir that was not well made script, there are lots of differences if you look carefully.you bump a thread from 2014 for another site than have a copy-paste of aleady existent post from 12 Mar 2018 on mikrotik forum???

The script i searched and posted captures and redirects properly even when ISP network is not online.
it also deletes existing clients which are logged in so that they know ISP is offline.
it add this
"/ip hotspot cookie remove [find];\"
which i missed and should have included.
if you use both you will realize the difference.
and i would have posted it together with my earlier post, in other thread but i was lazy and did not search hard enough for it, but thankfully you brought it up, if you have the privilege please merge my posts their.
Thanks.
