Hello! Recently my home network got additional network connection, so I decided to try using Zebra to see if the whole set-up would be simpler and easier to maintain. During the test period I've noticed that Netfilter "sees" locally originated multicast traffic as external-incoming one: [125488.045542] RAW: M: IN=eth3 OUT= MAC= SRC=172.19.20.2 DST=224.0.0.9 LEN=512 TOS=0x10 PREC=0x00 TTL=1 ID=0 DF PROTO=UDP SPT=520 DPT=520 LEN=492 (Caught with such set-up: *raw -A PREROUTING -d 224.0.0.9/32 -i eth3 -m pkttype --pkt-type multicast -j LOG --log-prefix "RAW: M: " --log-ip-options) IP-addr. "172.19.20.2" is a local one; it's assigned to interface "eth3". I'm not sure neither whether is this a bug or "feature" nor is this Netfilter's bug/feature at all -- more likely it's the kernel's issue. May be it's due to RIPv2/Zebra's "glitches"(?). What would you say? -- End of message.
