I have 2 internet connections and cisco 1841 is doing NATing , Now I need to add second connection (ADSL via Ehternet int), How can i tell router to use second connection
description *****LAN Connection to Switch*****
ip address 10.0.0.254 255.255.0.0
ip nat inside
ip address negotiated
ip nbar protocol-discovery
ip nat outside
ip nat inside source list 2 interface Dialer0 overload
ip route 0.0.0.0 0.0.0.0 Dialer0
If I just add second default route to new connection nothing flows via that interfce, I have tired putting two NAT interface Dialer0 overload command but only once commands stays and overwirte the previous command.
New route is something like 0.0.0.0 0.0.0.0 fastherethernet0/0 ( conncted to ADSL modem via ethernet)
If I do that router is not sharing that connection and every thing is going via Dialer 0 , Do I neet to modify NAT statments to make it work and how.
Thanks for the advise
Well you can configure your router 1841 to do policy based routing. First of all, you must define what kind of traffic goes where. You can compine policy based routing with object tracking, so you can use both interfaces to route packets and the one backup for the other. I am sending a sample configuration with one primary FastEthernet Interface and the secondary ADSL interface.
Hope this help you!
