Two isp in mikrotik

RouterOS General
1

Well, i have mikrotik 532A with 564. In eth1 is the first isp this connection comming from a cisco (i have the administration of this, an i have a whole clase c). eth2 is my lan, eth 3 is a switch with vlan port, eth4 is the second isp (but i don´t have administration of this an is a /29).

My problem is this:

In the switch i have clients with diferent ip address public without nat and privated using the first isp. An a second client coneccted to the second isp between a bridge interface (eth3, eth4) an using routing-mark to this client and some rules to work. It work properly but my problem is when y try to select an addrees of my lan (privated address) to use the second isp. I try an try an try but nothing… i see packet going out from this isp but dont going in. I use similar configuration but nothing. I think it don´t work because eth1 is not member of bridge interface. But i try this, i put eth1 in the same bridge but nothing. :confused:

I don´t want to do balance or nathing else, i only need to use the second isp for my lan.

Any suggestion? i read al the examples but nothing work. I use router os 2.43

Thanks in advance

Well i try first the configuration on my pc. An it works fine to browse on internet. But my problem is when i try to access to webservers on the some mikrotik routerboard but in another eth with the first isp. I can ping the url an it resolve the external ip, But i can´t browse or access to servers in the first connection. Here is my configuration.

Any body can tell me why i dont browse or access them???
