I am trying to ping from fa0/0(inside nat) through cellular interface(outside nat)
to 209.131.36.158(www.yahoo.com) but it fails.
As far as I see the debug output, LCP and PPP establishes successfully but fails to obtain IP address using IPCP.
And also generates TERMREQ which indicates ISP has terminated the call.
I tried changing the NAT configution but in vain.
Can anybody help me with this?

1 After you create a modem data profile cellular profile create command and configuring DDR on the cellular interface, send a ping from the router to a host across the wireless network.
2 If the ping fails, debug the failure by using the following debug and show commands:
debug chat
debug dialer
debug ppp negotiation
show cellular all
show interface cellular
show running-config
show ip route

Did you ever find an solution to this problem, our company is using the verizon HWIC as well and our disconnects are coming from Verizon (Jul 20 19:15:31 UTC: Ce0/0/0 LCP: I TERMREQ [Open] id 68 len 4 ) this is the debug message the router is receiving that causes the Cell interface to disconnect. it looks like the solution is to nat and ACL the Cell interface. Did you have any luck??
thanks
