ISP gateway and subnet addresses

Posted on 2011-02-25

Hello All,

I have a Linksys router with a static IP from Bell T1, and I am running SBS2008 with MSExchange 2007. I am switching over to the new Rogers Wireless 3G+ Erisson rocket hub.
My settings in the linksys router include all of the IP info from Bell and the nessessary port forwarding to allow MSExchange to do it's job. I would like to use Rogers just for the internet
connection with a static IP, which is running fine. The only problem is how to setup the linksys router to accept the new ISP static ip. Rogers seems reluctant to give me their gateway address and subnet mask. Do I just put the Rogers hub before the router and change the settings of the linksys router to "obtain IP automatically ?

Any help would be appreciated. I am moving the MX records to the new Rogers static IP at the end of today so I will have email on Monday.

Did you order a static IP address from Rogers Wireless? They should provide you this information if you did. You would bridge their modem, or if no modem you would put the new public IP into the Linksys and not have to change any port fowarding rules.

You will need to update your MX record like you said to that new public IP. You should also change any A records used for Email to point to the new IP.
