I would like to setup a fail-over interface to cable from my primary connection on the 1941 router.
I am unclear how to accomplish the NAT changes when it fails over. Any input would be greatly appreciated.
Setup: Using a 1941 router, with 2 Gig interfaces and an HWIC card giving 4 additional interfaces.
G0/1: LAN Connection – 172.17.100.1/24
G0/2: Internet – 184.108.40.206/29
Fa0/0/1: (Cable internet failover) 220.127.116.11/29
LAN has 3 Vlans behind this router:
NAT Rules Currently:
VLAN1 – NATs to 18.104.22.168
VLAN2 – NATs to 22.214.171.124
VLAN3 – NATs to 126.96.36.199
My issue: - NAT when it fails over to cable
Im using a route-map for NAT to internet (attached). Is it possible to NAT each VLAN to a different pool address on the failover interface as well in the event of an outage on the primary?
VLAN1 – NATs to 188.8.131.52
VLAN2 – NATs to 184.108.40.206
VLAN3 – NATs to 220.127.116.11
