Hi,
Case study
We want symmetric routing on router with Dual WAN.
We would like external ping to WAN1 replying with WAN1, ping to WAN2 must reply with WAN2.
We try routing mark with new table entry and add route 0.0.0.0/0 using routing mark. but no success
Does anybody has a samples config ?
regards

Its not an external ping if you have to start marking traffic.
If both WANS are active they are both pingable from the outside.
IF you are trying to ping them from behind the router that is not external and in reality you wish to more accurately ping the WANIPs from any location and have them respond appropriately.
Sorry, may be I miss explained the situation.
Default route are on wan1, if I ping from external the wan2 , return path is to wan1, ISP wan1 has a RP filter and drop packet coming from IP wan2.
I would like that external ping on wan2 use wan2 interface to reply , not wan1

Mark new incoming connections from internet based on interface, then mark routing for resposes to these marked connections. You can see it e.g. as part of this: https://help.mikrotik.com/docs/display/ROS/Firewall+Marking#FirewallMarking-Example3(PCC)
