I currently have a 2901 in place to do all the routing on my network. It's currently configured to do all static NAT routes to the main interface of GigabitEthernet0/1. This as you can imagine, works with no issues.
The issue comes in when we try to intergrate a EHWIC 1GE-SFP-CU card into the mix. This simply just adds another eth port to the router. It is configured as GigabitEthernet0/0/0.
I need to do failover between 0/0 and 0/0/0 so that if the main ISP goes down for some reason, it picks up on the LTE backup and keeps on trucking.
I have not been able to do this, at all. The routes are "hard coded" to one of 0/0's two IP address, so they look like: ip nat inside source static tcp 172.16.xxx.xxx 25 66.76.xxx.xxx 25 extendable. This does not play well with an kind of failover situation.
So to sumerize:
Cisco 2901 with card EHWIC 1GE-SFP-CU added on,
Primary ISP is GigabitEthernet0/0 - has 2 static IPs
