I have a situation.... I need to keep all my wan links running optimally!
I am thinking of implementing 2 ISP's (different) so that I have a backup line running to my router. From my router I connect to a pix.. then to the LAN and so on.
My question is what is the best way to do this if I want to dynamically allow traffic to flow in and out of the pix when a link dies on the router?
So effectively, if the main line dies, how can a make the router automatically route traffic to and from the pix through the 2nd wan link.
The reason is our authenication servers will be based a one site...we have multiple sites and if a link at any site dies it means users can't authenticate! This is design from up above that we have to live with and work around... crappy if you ask me but we have to come up with a solution to allow for minimal downtime.
The secondary line is our idea but we aren't sure how to dyamically change routes when one dies...
Thanks in advance and I look forward to hearing from you.
