Question

I am trying to establish a IPSec connection between a Cisco Router and AWS, using a RUTX09 internet carrier for the cisco 867 router.
If the cisco router have the public IP the VPN works, but when I put the RUTX09 between so the RUTX09 have the public IP and the cisco router is connected to the lan side of rutx09 it do not work.

RUTX09 is almost factory default. Lan IP is 192.168.1.1 and I have setup portforwarding 500UDP and 4500UDP from WAN to Cisco routers IP, 192.168.1.253.
According to Amazons documentation it should be UDP4500 for IPSEC VPN, so I do not understand whats missing in the RUTX09

Hi,

To give out a Public IP to another router you will have to use Bridge mode as your mobile connection operating mode on Mobile WAN. More information about bridge mode you will find here: https://wiki.teltonika-networks.com/view/RUTX09_WAN
