Have a problem I'm trying to get past without buying anymore expensive hardware - thought maybe I could find some ideas here.
Here's my question:
I have a Win2K server that's running exchange. We have 2 seperate internet connections - one is a full T1 and the other is a regular DSL connection. The DSL line is simply a backup in case the T1 goes down. That's not an issue in itself - I can telnet into our primary router - make a couple IP route changes and all the internet traffic goes out to the web via the DSL instead of the T1.
However; when we swtich over to the DSL - another problem surfaces. In order for our e-mail to keep flowing right, I need to call our ISP and have him re-direct mail to the DSL's IP address. Now, I can have him set up a secondary MX record to try if the main one goes down, but he's making it sound like he doesn't want to do this unless I can keep both connections live to the server all the time.
So - to sum it up. Is there anyway to allow incoming Telnet requests to port 25 on both internet connections all the time? Both connections are live right now - but if I attempt to telnet to port 25 on the server using the DSL connection, I won't get any reply (yes, forwarding on the router is setup fine). If I switch the gateway to the DSL it will work fine - and vise-versa.
I'm about 95% sure the problem is the gateway - is there anyway to get windows to accept connections coming from either gatway, all the time?
Hope I managed to convey my problem properly...
Thanks!
