1. A method, implemented by a security relay node in a Public Land Mobile Network (PLMN), the method comprising:
receiving, from a Network Function (NF) within the PLMN, a control packet to be provided to a further PLMN;
delegating, to a remote security node, a setup of a N32-c interface towards the further PLMN such that the N32-c interface terminates at the remote security node; and
relaying the control packet to a remote security node for delivery of the control packet, over an N32-f interface, towards the further PLMN, the remote security node being outside of both the PLMN and the further PLMN.
