Beginner for BGP implemantation

Tue Jun 19, 2018 2:20 pm

Hi, I'm new with the BGP implementation with mikrotik. I need some help in fine tuning the configuration. I've done some work on configuration part and I'm posting here it for checking purposes as we are facing some issues with website browsing. Kindly have a look on our configuration and reply if anything found wrong.

Our upstream provider is AirTel - 182.X.Y.186/30
For Bandwidth & User Management we use Smartguard running on CentOS6 - 103.X.Y.2/29

RouterOS 6.41.1
model = RouterBOARD 3011UiAS

/interface ethernet
set [ find default-name=ether2 ] comment=AirTel-WAN
set [ find default-name=ether3 ] comment=SERVER-LAN
set [ find default-name=ether4 ] comment=LOCAL

Probably you don't need to caching dns queries.

I've checked it dns caching is not storing anything, even the Allow Remote Request is unchecked.

What issues exactly you have with browsing?
There is a particular website on which we're facing the issue, it is http://amazesms.in/. We are able to access the home page of this website from our network. It asks username & password credentials for further access. When we input the username & password on this website, then instead of login success it always returns to the same login home page. We have cross - checked it the account with the same username & password credentials are working successfully on other networks.

common browsing response is little late, I expect it to be snappier on a 155Mbps link consuming only 50% of it during the peak hours.

Other Networks means Other ISP Network or Mobile data.

Then maybe your upstream ISP blocking this resource?
