RouterOS 6.32.3 - Ip/ Firewall/ Nat : how to use a dynamic ip ?

RouterOS General
1

Hi,

I use routerOS x86. I defined a nat rule, in IP / Firewall / NAT

my parameter are :
Chain : dstnat
Dst.Address : aa.bb.cc.dd
Protocol : tcp
DstPort : 80
Action : dst-nat
to address : 192.168.1.38 (it is my local server)
to ports : 80

Question :

the ip delivered by my provider, when my modem is connected, is dynamic.
so : aa.bb.cc.dd is different, each time the modem is rebooted.

how can I manage it automatically, in routerOS, in my NAT rule ?

I was thinking t use a dyndns address instead of an IP address, which seem to be not possible.

thanks for any tips
Olivier

Just use out-interface= action=masquerade, you don’t need to worry about what IP you have.
