NATTING question

Hi

I have some trouble with understanding some basics was wondering if anyone could help.

So I have this server which is on a cloud and not on my network lets call it A . ip:5.5.5.5

I have another equipment which is an epdu lets call it B: ip: 6.6.6.6

inbetween I have mikrotik router (IP 3.3.3.3) I was wondering what natting rule I have to configure on my mikrotik so that when I do a snmpwalk on my server I can get information thats on my epdu through my router.

the only way i can get this infomration for now is if I connect through pptp then request the information but i do not want to connect through pptp.

I tried using this configuration: chain:dstnat dst address =3.3.3.3 protocol =17(udp) dstport=161 action tab action=dstnat
to-address: 6.6.6.6
and then chain=srcnat dst address:6.6.6.6 protocol:17udp dst-port:161 action tab action:src-nat to address:3.3.3.3
