Help me

Hi …

I have a Mikrotik(A) server fully configured and i have my a real IP, and i have another Mikrotik(B) server that connected through my server to the internet.
I travel a lot and i have to access my other Mikrotik server(B) but i have no idea how to access it !!! any help please ?!

I am assuming that router a is connected to the internet and that router b is connected to router a. I also assume that you have multiple public (real) ip addresses available. So:
1- Add another public ip address to the interface that is connected to the internet.
2- write a NAT rule were the source address is your second public ip and the destination is your router b.
3- write another NAt rule were the source address is your router b and the destination is your second ip address.
presto/ chano you are done.
