We have a /29 from comcast and currently use two of the addresses in production.

Steps to install.
- Disconnected the current router.
- Attached ge-0/0/4 to our current network. (configured with the same internal address as the existing router)
- Added x.x.x.148 to ge-0/0/0 (x.x.x.148 is the production IP address assigned to our current router)
- the original testing address of x.x.x.145 was not removed from ge-0/0/0)
- Attached ge-0/0/0 to the modem
Everything broke.

Did You check before migration with Comcast if they allow ONLY certain MAC on Your cable drop, or any MAC is allowed?
If the former, then when You disconnected Your old router and connected a new one, the router' MAC obviously changed and Comcast could have rejected everything coming from new MAC.
SRX allows to configure an arbitrary MAC per interface, so next time You might want to make note of Your old router MAC and explicitly configure this MAC on SRX ge-0/0/0 before connecting to Comcast.
HTH
