On a router with two ISP connections running 7.12.1 I am using route marks to load balance the traffic between the connections.
To do that, in mangle prerouting I assign a routing mark based on per-connection-classifier=src-address:2/x
This works fine. There are two extra routing tables for the 2 ISP containing the default route for each, one of them is also present in table main.
(there is a second entry with distance 2 for the other ISP in each of those tables)

Now, I want to dst-nat some outgoing traffic to the local router. E.g. DNS requests to a certain external server have to be redirected to the local DNS resolver.
The problem I encounter is that traffic dst-natted to a local address is not reachable via those alternate routing tables. So it does not work.
How can this be resolved? I have attempted to add routes to the alternative tables but I cannot find how to add a route for a local address of the router in such a way that it is routed locally to the DNS service.
Adding route rules for the local addresses also does not work for this case. I think in v7 the logic has changed so that route marks go before route rules.
(the solution worked OK in v6 but I have changed some things in the route rules setup since then so it is not really representative)

I had hope that "redirect" would work where "dst-nat to the router address" would not, but there is no difference.

Good day Sir,
In plain english, do you mean you have two WANs conducing load balancing and now you at trying to figure out how to add LAN based servers in the mix............

I mean what I wrote above, nothing else. I know how to make a load balancing setup, but now I want to combine it with dst-nat of some "outbound" traffic.

Remember it is not a question about "how do I get my config exactly right", it is a question about concepts in RouterOS.
"how can I get traffic with a routing mark handled locally at the router"

With the proper mangling rules of course.................... what have you got so far!

I am not interested in discussions at this level, so don't expect a reply to them.
