I have 2 active interfaces, each from an ISP. SO one of them is the main ISP and the other one acts as a backup line. I configured both to be active, so load balancing will take place.
I also created multipath rules, so for some network hosts, they are routed to interface ISP1 and some to interface ISP2. This works fine so far.
Then I created static routes to route certain websites to one of the 2 interfaces I have, ISP1 and ISP2. The main interface in ascending order is ISP1 and the second is ISP2. I created a static route where I specified websites to be routed via ISP1 interface. I also created a second static route where I specified other specific websites to be routed via ISP2 interface. Both static routes rules are enabled.
Here is the problem. Nobody can browse the sites that I created in static routing to be routed to ISP2, which is the secondary interface. Anything I specified to be routed to ISP1 interface works fine. When I ping the sites that are routed to ISP2, the result is destination cannot be reached. The site will not load as if it is down. Is it because ISP2 is the secondary interface and you can't route sites to secondary interfaces?
I also tried policy based routing, and it also doesn't work.
Note: ISP1 is connected to ETH1 WAN port and interface type is ethernet standard, ISP2 is connected to ETH2 DMZ port, interface type Cable Modem DHCP. ISP1 is a G.SHDSL Modem, ISP2 is a ASDL Modem connected to phone line using PPOA. Both are active interfaces and internet connections are active.
