I am working on an issue with 3G where the connection drops periodically over an IPSEC tunnel. The signal in the area is strong but when this happens the ip address of the 3G card drops and has to be renegotiated. Verizon, the provider says that a possibility could be that the verizon network is seeing our private network (10.X.X.X) and dropping our connection. I don't know how accurate this is because we are not doing any split tunneling or NAT anywhere. However, I am willing to try anything to resolve this. I was told that there may be stateful commands to put in the router to make sure Verizon doesn't see the private network. Any Ideas as to what these might be?
Here are my cellular interface commands...
ip address negotiated
ip access-group inbound in
ip access-group outbound out
dialer idle-timeout 100000 either
dialer string cdma
async mode interactive
ppp authentication chap callin
ppp chap hostname [email protected]
ppp chap password 7 4682jj
crypto map ipsectunnel
Again, any help would be greatly appreciated.
