I have router 2801 with two WAN link.
One is with static IP address, and the other is with dynamic IP.
One subnet (management user) use one WAN link (static IP),
second subnet use second WAN link.
I want to do these.
If one WAN link go down (link with static IP),
the other will route traffic for that subnet.
All traffic should go across other, active, link.
and when it came back, it will again route traffic for it subnet.
I hope you understand me.
How can i do that?
I checked your config one more time. It's failing because you aren't NATng for those addresses.
You have a "source list G-nat" for dialer0 and G-nat ACL isn't listing those IPs for translation.
