Mikrotik Help (Two ISP accounts for different devices)

[mister]

Hi all,

I have one network range: 192.168.0.X
Two ISP accounts: ISP1, ISP2

I want a subset of the range to use ISP1 and another subset to use ISP2

I've configured:

Firewall / Address Lists
Address List1: 192.168.0.1-192.168.0.10
Address List2: 192.168.0.11-192.168.0.20

DHCP Server:
Assigned static DHCP addresses

Interface:
Created two pppOE connections (Both Default Route Off)

Firewall/NAT:
Created two masquerade rules for ISP1/ISP2 each

Firewall / Mangle:
Chain: Prerouting, Src Address List: List1, Action: Mark Routing, RMISP1
Chain: Prerouting, Src Address List: List2, Action: Mark Routing, RMISP2

IP Routes:
A static route for each ISP with the respective PPPoe connection as the gateway, and a routing mark (RMISP1/RMISP2)

This works fine, and both incoming and outgoing traffic on the different range subsets is using the correct ISP,
but because I have no default route my Mikrotik can't do DNS lookups or anything.

I've tried adding a default route, with a higher distance, but then my outgoing traffic for each subset of the range goes out via the default route instead of the respective ISP.

I've been struggling with this for two days and I've officially given up. Can anybody point me in the right direction?
