pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/35166?usp=email ) Change subject: hnbgw: Allow announcing a different mgw-local IuUP address after MDCX ...................................................................... hnbgw: Allow announcing a different mgw-local IuUP address after MDCX This will allow emulating an MGW deciding to change its local IuUP IP address due to received remote address in MGCP MDCX, and announce the changed address back in MGCP MDCX. A test validating this scenario against osmo-hnbgw will be added in a follow-up patch.
