Hello,
I'm sorry for ask this stupid question, but I can't find a answer
I'm working on this scenario:
LAN-to-LAN ipsec conections, hub and spoke topology.
A central site with a 7100 router,10 remote sites with 806 routers (ADSL or
cable connections).
1.1.1.0-- (7100 Router)- 11.1.1.1 ------- INTERNET ---------- X.X.X.X
(806 Router)-- 2.2.2.0
|
|
-
--------- Y.Y.Y.Y (806 Router)-- 2.2.3.0
My problem is that the 806 public IPs are dynamic and it can change every
time that the 806 router restart.
If the remote site IPs are dynamic, how do I can route the traffic from the
central site to the branch ofices?
I can configure the central router to accept dynamic connections with a
preshared Key (for example), but Idon't know configure the central site to
reach the private LANs of the remotes sites after the connections are up.
The CISCO examples always use a route to the remote LAN through the public
IP (X.X.X.X) of the remote sites, but I can't use it on this scenario
because it could change .
Thank you for your help and your patience (as I tell you it was a stupid
question).
Juan
