[afnog] Routing Issue - Please Help

[Austin Uwudia]

Hi Dewole,
Its really nice to hear from you again. Thank you indeed for your response
to my query.
Thank you for the 1st line in your response; it just gave an insight. I
drilled down the NAT rule and found that I did not make explicit rules for
the different subnet. I just did and the problem is resolved.

Thank you very much and also to Scott who also responded. I appreciate.

Best regards,

Oga Austin,

What specifically do the NAT rules on your Mikrotik router say? It is
possible that your routing is fine but since you have a NAT rule
specified, the connections will be NATted as per your instructions.

Do you have any redirection to a web proxy running on that Mikrotik
perhaps? Whatismyip will only show you the IP of the machine that made the
http connection.

Open an SSH session to a server on the Internet and see what IP it shows
you as connecting from. That should give you a clearer picture.
