I am hoping that this is something someone has done before, Im sure that I cannot be the only one out there wanting this, but I have searched through whitepapers and guides in looking for some help in my current problem.
How do I create a multihomed NAT ?
I have tried to setup 2 NAT pools, but when I shutdown the routes to the primary interface it doesnt fall over to the backup route.
I have read that the reason it doesnt actually fall over to the secondary pool is due to NAT needing to flush the translations on the interface and the only way to do this is to have a interface down.
Would using one of the new 12.3T tracking features help with this ?
Another method that has been suggested is NAT on a stick, but I have been unable to find a simple guide on how to configure this.
We have a 1801 router, our primary ISP link is a 4meg/4meg connection this is a Ethernet handoff which goes direct into FA0. We also have a backup ADSL link which is supposed to be used when our primary link goes down. Whilst this doesnt happen all the time, the use of VOIP within our network means that we now need connectivity to the internet at all times.
Unfortunately neither ISP will allow us to do any kind of BGP without us paying a fortune.
If someone could give me some hints / howto guides, I would really appreciate it.
Once the packet is Nated. It is routed based on Routing Information Base(RIB). And if the interface goes down, the ip route tied to that interface will be withdrawn from routing table and hence no more nat will happen across that interface.
So the interface needs to be classified as down for it to change to the backup NAT interface.
