[44net] RIP broadcast does not reach my GW

Good afternoon, Since this morning it seems that no RIP broadcasts are reaching the commercial IP address of my GW. I've running ampr-ripd-2.4 in debug and verbose more for all of the afternoon, but I see nothing. I also checked the firewall rules (there are none) and also tried tracing packets with tshark. None of the methods should any RIP UDP packets arriving at my GW. The GW entry seems to exist at least since 2020-11-11 14:16:42, so it's not a new entry. A tracepath from the GW to 44.0.0.1 stops at sdsc-7710-7--mcore-vl2995-p2p.ucsd.edu (132.239.255.50). Did anybody notice anything similar? 73 de Marc, LX1DUC
