Networking Improving

I got 3 internet connection 2 DSL and 1 Cable.
I need to connect all of them to one device but to have only one online and the other like a backup connection and when one get down the next go up automatically.

Re: Networking Improving

are all these connections from the same vendor? if this is the case OSPF is probably the solution you want. failover would be mostly transperent.

if not, a NAT proxy might be you're only choice. you'd set up a nat proxy, define the routing to use one first, and other if fail.

when one goes down, the others will pickup, but all connections will be reset.

Re: Networking Improving

I think the 4port module is not a routing interface, but i could be mistaken.

Check with your provider and see if you can run RIP, OSPF, or BGP with them. If so, you'd configure an interface for each of the networks and publish dynamic routing info out to the various ISPs. Be careful to configure the routing protocol to disallow packets from one Isp to another.

Do you have an IANA IP Range? Youâ ll need to get on
