Hello,
I'm trying to make multihoming on cisco 892 router.
I Managed to build configuration which works as I wanted but I ran into problem which I can't solve till now.
I'm trying to do port forwarding on cisco with 2 working WAN interfaces.
Configuration:
interface FastEthernet8
description ISP_B
ip address 192.168.150.10 255.255.255.0
ip nat outside
ip virtual-reassembly
duplex full
speed auto
!
!
interface GigabitEthernet0
description ISP_A
ip address dhcp
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
!
!
interface Vlan1
ip address 192.168.100.1 255.255.255.0
ip nat inside
ip virtual-reassembly
!
!
ip forward-protocol nd
no ip http server
no ip http secure-server
!
!
ip nat inside source route-map ISP_A interface GigabitEthernet0 overload
ip nat inside source route-map ISP_B interface FastEthernet8 overload
ip nat inside source static tcp 192.168.100.100 22 19.168.150.10 65022 route-map ISP_B extendable
ip nat inside source static tcp 192.168.100.100 80 192.168.0.199 80 route-map ISP_A extendable
ip nat inside source static tcp 192.168.100.100 22 192.168.0.199 65022 route-map ISP_A extendable
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0 192.168.0.1 10
ip route 0.0.0.0 0.0.0.0 FastEthernet8 192.168.150.1 251
!
route-map ISP_A permit 10
match interface GigabitEthernet0
set interface GigabitEthernet0
!
route-map ISP_B permit 10
match interface FastEthernet8
set interface FastEthernet8
Interface gig0 have IP 192.168.0.199 in my lab environment.
Problem is with when I'm using gig0 as gateway of last resort all packets which arrive by fe8 interface are sent by gig0 interface and I can't access any devices by second link.
I was trying to use different approaches to force that traffic to come back on same interface by which it came in but up till now I haven't got any luck with that.
Have anybody done such a thing in past or is this even possible?
