We want to connect as follows:
Internet <--> ISP PPPoE DSL Modem <--> Cisco 881 (DMVPN) <--> Cisco 871 (IPSec VPN) <--> LAN1 (Private)
<--> LAN2 (private)
We have 1 DSL internet connection and 2 Static IP's through PPPoE and 2 unique ID's and passwords.
Currently we have the Cisco 881 with 1 IP and have an outside DMVPN connection to another location.
We want to add another Cisco 871 to inside of the 881 for a different LAN. If it can be done?
How does the PPPoE have to be setup by the ISP (Currently PPPoE providing 2IP's using 2 usernames and passwords)? No problem if the routers are set up in parallel with the DSL modem.
Can we simply define a PPPoE passthrough on the 881 so the 871 gets a public IP or do we need to apply the 2 IP's to the 881?
We are stuck on how we should approach this from a design standpoint? Details come later.
