I have an 1841 doing failover. Primary connection is static DSL and secondary connection is cable. The router fails over smoothly to the cable connection every time dsl goes down. Then it goes back to normal once dsl is up again.
What I need is to be able to do the same thing BUT on a cheaper router, perhaps one of the 800 series routers.
Do you guys know of one that can do the same trick and that has at least 3 physical interfaces for this ? (one for primary, one for backup, and the other one for the inside network)
If I may, can I inquire as to whether or not the failover on your 1841 fails between two OWNED IP blocks OR are the IPs received dynamic. I am having a problem on an 1841 when it fails from a T1 to a DSL line .. The router can ping but no devices behind it can ..
My primary connection is a T1 (static) and my backup is a Cable (dynamic) connection
The problem you are having sounds familiar. During my testings phase, when the router failover to the cable, I couldn't ping anything on the outside. There was a line which the cisco tech told me to remove and it worked. I don't remember which line was it, but if you post your config, I will point it out to you
But going back to my question, can anyone recommend a router, other than the 1841, to do failover? I am looking for a lesser and less expensive router
Get a cisco 877. Use the DSL port for your DSL connection and then you have 4 fast ethernet ports. Make a specific VLAN for your cable connection and assign it to one of the 4 fastE ports. Works for me.
