According to https://github.com/ethereum/devp2p/blob/master/discv4.md#neighbors-packet-0x04, the correct order of the node record fields is
[ip, udp-port, tcp-port, node-id]. The port fields were swapped in ourNodeRecordstruct, which caused to Reth use the TCP port during discovery, causing it to fail if the port numbers are unequal.
