Vodafone sim with Access control list won't allow connection to NRF Connect


I'm trying to connect to nrf connect with the nrf9160 DK. I am using an Irish vodafone NB-IOT sim to establish the connection. This sim has an access control list, which means it can only communicate with a predefined list of ip addresses (8 max). This is tricky for connecting to nrf connect because I seem to be connecting to different addresses each time I try to connect to nrf connect and then the sim won't allow the connection. Is it possible to connect to one or a small range of ip addresses on nrf connect so that my vodafone sim will allow the connection?

(I know there's a few too many connects in that paragraph!)
