Change public IP every 60 sec

RouterOS General
1

Hi,

I have 10 public IP’s on my MT, and i would like change IP’s every 60 sec for new one ( per user ).
I use Src-nat 192.168.1.0/24 → same 212.212.121.10-212.212.121.20 ( Not by Dst )


192.168.1.10 — > 212.212.121.10
after 60 sec
192.168.1.10 — > 212.212.121.11
after 60 sec
192.168.1.10 — > 212.212.121.12
after 60 sec
192.168.1.10 — > 212.212.121.13
after 60 sec
…
and 192.168.1.10 — > 212.212.121.10 ( back to first IP )

Anybody know how to do that ?
I wonder about Per Connection Calssifier but don’t know is it good way

Do you think it is smart? What do you expect that happens with the running connections?

You can do it by scripting if you need the timing.
Of course you realize it’s going to interrupt all outbound TCP sessions every 60 seconds?

No, this is for new TCP sessions.
Do you have any script example ?

I can do otherwise, refers to RA VPN connections ( this is main problem )
VPN user needs to receive a new IP address after disconnecting and re-connectivity. At the moment it got the same IP until another user ( user_2) got the same internal IP address from VPN pool as user_1
I noticed that the public IP address is associated with the internal VPN pool IP’s

192.168.1.10 → 212.212.121.10
192.168.1.11 → 212.212.121.11
192.168.1.12 → 212.212.121.12
