Firstly to allow users to keep their current installations working, secondly it also makes sense in lab or non-complex sites to just pass GTP through without a UPF. The same is true for RTP proxying, next time i test 3G with a lab setup i will be annoyed that the hnbgw *requires* an MGW, and will rather submit a patch to make MGW optional and allow running as it did before RTP proxying File include/osmocom/hnbgw/hnbgw.h: https://gerrit.osmocom.org/c/osmo-hnbgw/+/28816/comment/1f75cf19_ef2877b5 PS1, Line 193: static inline bool hnb_gw_is_gtp_mapping_enabled(const struct hnb_gw *gw) "mapping" == "proxying" ... should we decide on one of those terms?
