Switching ISPs - Ethernet 2 port is not working the same as eth 0/1

Hello, my company is switching ISPs, we have a new static IP for the new internet. I still have access to my old internet and the old static IP, being used on ethernet 1. I updated ethernet 2 to match the same settings, besides the ip address. I can see get to the AdTran front end from the internet using the new static IP. However, as soon as I disconnect the old ethernet line, I can not longer get access to the AdTran and the calls do not hit the ad-tran using the new IP on ethernet 2. I updated the ethernet 2 media gateway to be the primary and removed it from ethernet 1. Any suggestions would be appreciated.

ACORNTYLER,

Using the limited information in your post and no "show run" configuration, it sounds like you have a basic IP routing issue associated with the IP Default route in the TA900E.  Here is an example, the "ip route 0.0.0.0 0.0.0.0 AAA.BBB.CCC.DDD" command also needs to be updated.

!
interface eth 0/1
description “OLD ISP WAN”
ip address 64.60.225.2 255.255.255.252
no shutdown
exit
!

ip route 0.0.0.0 0.0.0.0 64.60.225.1

!
interface eth 0/2
description “NEW ISP WAN”
ip address 24.199.235.2 255.255.255.252
no shutdown
exit

!  THE CHASSIS DEFAULT IP ROUTE WILL HAVE TO CHANGE POINTING TOWARDS THE NEW ISP'S ROUTER.
ip route 0.0.0.0 0.0.0.0 24.199.235.1
!

 

Hope this helps.
