Hello everybody. There is such a problem: I have two SSID of the network, different subnet. There are two VPN tunnel: One PPoE from the provider, the other from my L2TP server.
Problem: Users who use SSID1 to have to go into a tunnel PPoE provider. Customers who use SSID2 should go into L2TP tunnel.

What I've done:
1) IP - Firewall - Mangle mark the package
2) On the basis of the marking. IP - Route forwards the packet to a particular gate. (For exemple: dst 0.0.0.0/0 and MARK "ssid1" go to gate PPoE_ISP)

Problem:
My Mikrotik cannot raise L2TP tunnel. I think the problem is that the packets the router is not as marked with the.
