I am in the beginning stages of testing a CISCO831 Router on A DSL Line I have in my office. I want to be able to us the DSL Line as a backup for my office network just in case the frame relay the office uses to connect to the WAN suffers an outage. The problem I am having is that I am unable to connect to the internet via my default gateway when I use a different ip address (10.10.10.3) as the default gateway within the same subnet as my assigned router ip address (10.10.10.1). subnet mask is 255.255.255.0 .... any ideas or comments on how I can fix this problem would be appreciated ... if more information is required please let me know ... Thank you ....
