Hey all,
Just wondering if someone can shed some light on functionality of a routed cellular interface on a Cisco 899G-LTE router. We presently are running these at a few sites and only use the embedded cellular for failover, and the wired WAN port 99.9% of the time. We have a default static route out the WAN port, but using some IP SLA's for reachability out to a few IP addresses we can determine if the WAN connection has failed, and it will drop to using a new default static route that typically has a lower priority than the main route. The new default static route is just out Int Cellular0. Our wired WAN port is connected to an upstream firewall and the firewall is complaining about IP spoofing as it is somehow seeing the IP of our Cellular interface coming into the ASA from the Wired WAN path.
Maybe it has something to do with my interface config?
interface Cellular0
ip address negotiated
ip access-group cell_access_in in
no ip redirects
no ip proxy-arp
ip flow ingress
ip nat outside
ip inspect fw-inspection out
ip virtual-reassembly in
ip verify unicast reverse-path
encapsulation slip
ip tcp adjust-mss 1200
load-interval 30
dialer in-band
dialer idle-timeout 0
dialer string lte
dialer-group 1
no peer default ip address
async mode interactive
crypto map TunnelToCompass
routing dynamic - Not sure if this is necessary seeing as we are using default static routes, as explained with the IP SLA's above?
