NAT and Routed Network with Two ISP's on one router
I'm sure this has been done covered many times, but I am not finding it.
I have two ISP connections.
With ISP-A I have a /30 between us and 126.96.36.199/24 is routed to me via the /30 for thsi example we will say the /30 is 188.8.131.52 on isp end and 184.108.40.206 on my end
With ISP-B I have a 220.127.116.11/29 subnet. and the ISP gateway is on that subnet at 18.104.22.168
On the inside of my network I have devices using both 200.100.100.x addresses and devices on 192.168.100.x that need to use NAT.
I would like all of the devices on 200.100.100.x addresses to continue using ISP-A as their gateway.
Everything on 192.168.100.x should use NAT and go out ISP-B
I have tried
ip nat inside source route-map ISP-A interface GigabitEthernet0/1 overload
route-map ISP-B permit 10 match ip address 101 match interface GigabitEthernet0/1 set ip next-hop 22.214.171.124 ! route-map ISP-A permit 10 match ip address 111 match interface Multilink1 set ip next-hop 126.96.36.199
The problem comes when I have default routes to ISP-A in the router than none of the ISP-B traffic works, and vice versa.
