Is natting working on 4.2 with RB433 and firmware 2.23. Or do you need to do something wierd to get it to work ? Using src-nat and just and accept and can't get it to hit the rule

Nat is working without problems on all versions.
More information is needed. Do you use bridge? Also post your nat rules.

Running 4.2.

Seems to be working now. I had simplified the rule to the point that it was a src-nat chain. Matching anything with an action of accept. Is seems to now be getting a packet count.

Though is is still far less than a filter rule of the same.

ie forward rule has match 30000 packets and the src-nat has matched 550 over the same period. Is this expected ?

NAT is matching only tcp syn packet or first packet of connection, but filters see all connection related packets.

Don't know what happened but glad its now working Tried the same rule on 3 diffrent router boards and it didn't work. Now tested on two of them and its working again most probably a pebcac error

also when connection is already established it will not be matched by newly created src-nat rule. You have to clear connection table and reestablish connection.

That could be it thanks
