Redirect l2tp through IOS router to ASA (dynamic IP clients...)
I have a 877 ADSL that goes from WAN > DMZ > ASA > LAN. Essentially the LAN side of the 877 is a 192.168.0.0/28 subnet, and on that subnet is the WAN side of the ASA5505 (that has a 192.168.2.0/24 LAN).
I had set up a dynamic L2TP that I tested going from another router on the 192.168.0.0/28 to the ASA. Problem is when I am outside trying to connect through the 877, i.e. actually out on the internet, I can not connect. I am unfamiliar with IOS routers in this regard. I looked for a solution and found documents on vpdn redirect. However they were brief and not fully explain whether this is a solution. If I do vpdn redirect source, this would not work for dynamic l2tp would it?
On the 877 I created static nat:
ip nat inside source static esp 192.168.0.3 interface Dialer0
Now prior to this I was able to PPTP in. I had static NAT for PPTP to another device (Linux PPTP server) that was on the 192.168.0.0/28 subnet (877 inside). So I am wondering if A. I do not have l2tp dynamic configured properly on the ASA, B. I do not have l2tp redirect properly configured on the 877, C. If I just am not able to do this with l2tp and should go back to using PPTP.
