  • Port forward 514 to 5514 does not work

    Posted on

    Hi

    In my firewall configuration i have this:

    public (active)
      target: default
      icmp-block-inversion: no
      interfaces: lo VLAN3030
      sources: 
      services: ssh dhcpv6-client
      ports: 9200/tcp 9300/tcp 5601/tcp 1026/tcp 1026/udp 514/tcp 514/udp 5514/tcp 5514/udp 5600/tcp 9600/tcp 6514/udp 6514/tcp
      protocols: 
      masquerade: yes
      forward-ports: port=514:proto=udp:toport=5514:toaddr=
        port=514:proto=tcp:toport=5514:toaddr=
        port=514:proto=udp:toport=5514:toaddr=127.0.0.1
        port=514:proto=tcp:toport=5514:toaddr=127.0.0.1
      source-ports: 
      icmp-blocks: 
      rich rules:
    

    But i don't have information from port 5514 only by the 514, you can see with this command:

    tcpdump -n -i VLAN3030 dst port 514 2>&1
