Hello !
We habe some locations with very slow DSL connetion (< 200 kbit). Some services need direct vpn-connection to the datacenter and some RDP access etc. - the networks are connceted with LAN-to-LAN ipsec tunnel. Work's fine with slow speed.
Now we like to set up one side with LTE. Did someone set up ipsec with one side via LTE via Telekom or Vodafone in Germany ?

Yes, both works! We used the vendor modems and connect to IOS routers. Then we configured the links as backup EasyVPN connections.

@ciscomax
You uses EasyVPN to get a LAN-to-LAN connection ?

Sure, with network extension mode, works great. But only for lte cause of thy dynamic ip adresses.

Ok. Never configured the "network extension mode". Can you drop the relevant part of your configuration? What Hardware and IOS do you use?

Sorry, was on vacation, do you still need the config parts?

Hello!
I'll be happy about a working config with Vodafone. Actually our Chat-Script ends with: "Chat script lte finished, status = Connection timed out; remote host not responding"

We use the B1000 from Vodafone to do the LTE stuff and behind it is a IOS router.
I can only provide D1 Chat Script (3G) from another project:
chat-script gsm "" "ATDT*99#" TIMEOUT 30 CONNECT
interface Cellular0
no ip address
ip flow ingress
encapsulation ppp
no ip mroute-cache

PIN:
router#cellular 0/2/0 gsm sim unlock 6543
Create the profile:
router#cellular 0/2/0 gsm profile create 1 apnname.net
AT command is
ATD*gprs_sc*CID#
or
ATDT*gprs_sc*CID#
where gprs_sc (GPRS service code) is 99, but 98 can also work. T-Mobile says 99, Cisco docs contain 98.
Some modem manual says:
request to use the Packet Domain service.
request to use the IP service
CID (PDP Context Identifier) is the connection profile number (see show cellular 0/2/0 profile ), number between 1..16 This profile contains the APN name.
Typical AT command is: ATD*99*1#*
(Or simply *99# , default CID is obviously 1 )
I don't think you need a chat-script:
interface Cellular0/1/0
no ip address
encapsulation ppp
load-interval 30
dialer in-band
dialer pool-member 1
dialer-group 1
async mode interactive
!
interface Dialer0
ip address negotiated,
no ip redirects
no ip proxy-arp
encapsulation ppp
load-interval 30
dialer pool 1
dialer idle-timeout 0
dialer string "*99*1#"
dialer persistent

no cdp enable

Troubleshooting:
sh int cell0/0/0
sh cell 0/0/0 all
(config)#service internal
(config)#exit
#test cellular 0/0/0 modem-power-cycle
