switching broadband services with a single sbs2011 server
Posted on 2012-03-12
We have a single sbs2011 server, and we also have 2 broaadband services for redundancy.
Unfortunately, we are having problems with our first service, and want to switch it to our second one.
Having changed the connection on the primary router, we now have a different static IP. I have changed the DNS settings at our ISP to reflect this. Having done so, we find that the new static IP address is black listed. (we know the reasons for this now).
We currently have internet connections which is helpful, but our e-mails are bouncing back stating that the static IP is black listed. Is there any easy way to redirect outbound mail through the faulty IP?
We have the original (faulty service) connected to a router using a different local ip address ie 192.168.1.254 rather than 192.168.1.1. The service is up then down every few minutes, but may be sufficient to get us through till the service problem is resolved.
I want to keep the internet connection going out through 1.1 (the associated static IP is black listed but OK for internet connections) and have the mail go out via 1.254 (the service is intermittent, but the static IP address is OK).
Can this be done??
Is there a way to provide automatic redundancy, so that if one service fails, the other kicks in and provides both Internet Services and e-mail services for exchange.
We are obviously trying to get the faulty service operational, but till then we could do with a workaround.
