[FIREWALL] Usage of "random" function

RouterOS General
1

Hello,
I was checking out the “random” function in the FIREWALL/NAT wiki and doesn’t explain any further.
Anyone can tell me how this function works?

Thanks in advance!

The wiki DOES explain it.

random (integer: 1..99; Default: ) Matches packets randomly with given probability.

That’s the only explanation in the wiki. I don’t understand it so well because there’s no example.
Can you give me a hand with this? I just want to redirect every X web connection attempts from an internal bridge to the outside, the dst-nat rule redirects the query to an internal webserver and in the next connection attempt, they can navigate outside and so on.

Thanks in advance

If you add a rule with random 50, then 50% of any packets that will go through this rule will take the action that is specified for this rule.
For other 50% of packets, this rule will act as if passthrough was the action. (the packets will not hit the rule)

Thank you very much!

Have a nice day
