hi
how i want use src-nat and d-nat in same time how i can configure it in Mikrotik
You simply configure it, it will work in the same time. You configure dst-nat rules in “dstnat” CHAIN, and src-nat rules in the “srcnat” CHAIN. Each IP packet goes through the dstnat chain after getting inside the router (before routing decision), and goes through srcnat chain before leaving the router. So both the src-nat and dst-nat rules will be applied.
