Check whether you are using any extra personalised features of your fixed Home BB router. Some may not be supported by the EE mobile network and/or router.
E.g. Do you run a server on your LAN? The EE mobile network uses Carrier Grade NAT (CGNAT), which means that you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB.
