hello ,my big problem is a goverment website in wich the private company upload tenders documents,the problem is when 1 real ip is routing with mikrotik and in the client computers is privat ip the client can not upload files,when i route with a simple router work perfectly the files are uploaded ,can you give me a solutions?
the webpage is www.app.gov.al
Go to ip/firewall/nat and create a rule like:
chain=srcnat
out-interface=yourinternetinterfaceintherouterboard
src-address=192.168.1.0/24 (your network)
action=masquerade
configure gateway in IP/routes
Configure DNS in ip/dns
I made these things,i am not new in mikrotik routeros,all webpage work perfectly except www.app.gov.al When customers try to upload tender documents,in a simple router with simple work perfectly!!!
when your private IP cross the mikrotik, then this connection uses the public IP…
To test the internet is working fine, configure ip, route and dns and use the hotspot wizard to create a user and enter via hotspot. IT MUST WORK.
If it work, then the manual NAT config must work too.. It’s not a difficult config. It’s very strange this don’t work.
i have proved with hotspot and with ppoe server-client and the some problem,is very strange that with a simple router work without problem !!
Perhaps the website uses a strange port, but it doesn’t matter.. : /
If you enter to the hotspot, you can see google/youtube/facebook and all the other websites and you can’t enter this government site? 
thanks for your support 
,
