Hi guys,

Can someone help me with the following setup:

I have 2 ISP. Let's call the ISP1 and ISP2.

ISP1 give us 2 static IP addresses secured by MAC
for example:
10.10.10.104
10.10.10.105
ISP2 give us 1 static IP addres secured by MAC:
20.20.20.1

Also we have 2 local networks. Let's call the LAN1 and LAN2. They need to use the 2 separate IP addresses that ISP1 provide us with and also both LAN networks need to have ISP2 as fallback.
LAN1: 192.168.10.0/24
LAN2: 192.168.20.0/24

Because that the ISP1 uses one port of the MikroTik and need to have 2 diferent MAC addresses I added a bridge to the Ether1 with a masquerade for it but now everything goes through the IP that the bridge gets (10.10.10.105) . I try different setups in the last week but if the network manage to work at all it always goes through the bridge's IP address.

I will close this because I accidently post it twice.

Create 2 virtual interfaces in metarouter and bridge them to ether1, create 2 meta routers and add vif1 to mr1 and vif2 to mr2.

Create another 2 virtual interfaces and assign vif3 to mr1 and vif4 to mr2

in mr1:
add to ether1(vif1) ip 10.10.10.104 with desired mac
add to ether2(vif3) ip 192.168.10.1/30 for example
masquerade everything with output interface ether1
don't forget to configure firewall

in mr2:
add to ether1(vif2) ip 10.10.10.105 with desired mac
add to ether2(vif4) ip 192.168.10.5/30 for example
masquerade everything with output interface ether1
don't forget to configure firewall

in main router:
add ip address to vif3 192.168.10.2/30
add ip address to vif4 192.168.10.6/30

----------------------

now you have gateway 192.168.10.1 on vif3 and 192.168.10.5 on vif4 and you can make PCC load balance with them or whatever

Hi again,

I'm trying the suggested configuration but when I try to add the second metarouter i receive a not enough memory. So probably this model (RB750GL) do not have enough Ram memory to make to metarouters.
So is there any other way to achieve this results?
