Re: redundant wan

From: "archie" <archie@xxxxxxxxxxxxxxxxxxxxxxxxx>

| We have two connections to the internet (1 T1 and 1 DSL) setup for redundancy
| purposes on a router with 2 wan ports. These connections both have their own
| pool of IP addresses. Our name resolution is setup to point to IP addresses
| bound to the T1. We recently had a situation where our T1 went down and we
| had to disable that WAN port on our router until it was available again. In
| this process we found that we needed to setup a second ftp subdomain
| (ftp2.mydomain.com) and tell our customers to use that name.
|
| My question is how can we make it so that we don't have to notify our
| customers to use the other subdomain should this happen again without having
| to make dns changes. In other words, if ftp.mydomain.com is bound to our T1
| on 65.1.1.1 and out T1 goes down, what would we need to do to make sure
| ftp.mydomain.com goes through our DSL line bound to 64.1.1.1 (IP addresses
| are not real, just examples).
|
| Would we need to change our topology, or is there a way to set a secondary
| IP or route for our dns names? Any feedback is much appreciated.
|
| Thanks,
| Marc

This is a networking question, not a security question.
Plaese ask in a networking or router based news group.

Off the bat, I'd say you need a Router with with two WAN ports.
