Comcast Static IP with pfSense

I am relocating my office (both Comcast business accounts)  and I currently have a static ip with a pfSense firewall. Old office has ip a.b.c.33 / 30 and we set the pfSense up with IP a.b.c.33 and gateway a.b.c.34 . The new office we have been given Ip a.b.c.230 / 30 and was told our usable ip is a.b.c.229 .  We also have a Cellular backup device between the Comast router and the pfsense. So my initial setup in the new office was pfSense wit IP a.b.c.230 and gateway a.b.c.229.  Not working. We called support and they said tech made mistake our ip is a.b.c.229 and gateway is a.b.c.230. Reconfigured not working. Called support again and they were not sure and did not want to reconfigure our devices so here we are. I have since eliminated the cellular failover box from the equation and connected directly into wan on comcast modem. When laptop is connected to lan1 it gets a 10.1.10.1 iP and reverse IP lookup returns a.b.c.230 as internet facing IP address. pfSense still no access in WAN port but laptop can get out.  I have two questions, 1) I think there a misunderstanding of our given IP/Gateway because I can ping (from home) a.b.c.230 but not a.b.c.229. If the convention is the same as old office gateway should the new gateway be a.b.c.231? Could the comcast static IP be set up improperly?
