I checked several times, the ip address is correct and the firewall does not have any rules about the lan network segment

[13werwolf13]

i listen network traffic by tcpdump

i don't understand

20:43:59.204477 IP NOT_LAN_IP.39576 > 192.168.196.246.54321: UDP, length 32
20:43:59.204507 IP NOT_LAN_IP.39576 > 192.168.196.246.54321: UDP, length 32
20:43:59.204536 IP NOT_LAN_IP.39576 > 192.168.196.246.54321: UDP, length 32

NOT_LAN_IP - another server ip address from another interface & another network. if i ping 192.168.196.246 traffic going to right interface from right ip..

UPD: Apparently this is either an artifact of tcpdump display or something else, I noticed that there is a lot of such traffic with a seemingly incorrect outgoing ip but going without errors. I'll leave this comment because it may be useful, but I don't think it's relevant.
