recently i?ve purchased a 1801 for enable an isdn backup for my internet access via ADSL.
My first problem is that i need to use NAT to gain internet access from my network behind, but i don?t wnow how to proceed for enable it for ADSL and bri interfaces simultaneously because when the main ADSL interface goes down and bri comes up, i will need NAT too.
I?ve tried configuring the 2 static translations but only run the last configured and the first is ignored.
I can?t create a pool because my provider give?s me a dynamic ip address when the isdn link comes up
thank you very much
