Duplicate ports allowed



  • If I have a NAT rule and then copy it I correctly get the error
    "The external port range overlaps..".

    Now if I have a rule with TCP/UDP and then copy it but with just TCP this is allowed, even though it should not be allowed.

    e.g.

    I have

    If Proto       Ext. port range NAT IP                             Int. port range
    WAN TCP/UDP 25 (SMTP) 10.10.10.62 (ext.: 2.2.2.2)      25 (SMTP)

    I can add

    If Proto       Ext. port range NAT IP                             Int. port range
    WAN TCP      25 (SMTP)           10.10.10.62 (ext.: 2.2.2.2)      25 (SMTP)

    and have both rules live at the same time.

  • i think the gui only checks when you have 2 rules of tcp or 2 of udp or 2 of tcp/udp but not a mix

    but its not a problem the first rule wins the other is never seen
