ACL Violation when attempting WAN to LAN NAT v19.5.0

Hugh Beavis

Hello

I have searched and can see others have this issue, however none of the solutions have worked for me so far.

I have followed the steps at https://docs.sophos.com/nsg/sophos-firewall/19.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/RulesAndPolicies/NATRules/RulesPoliciesCreateDNATAndFirewallRulesForInternalServers/index.html#specify-the-nat-rule-settings to create the following policies, with the intention of allowing WAN -> LAN traffic the specified ports:

Valheim Server is an IP 172.16.50.110

    Hi again

    I've tried the each of following configurations on the firewall rule, all to no success - I still see Violation / Local_ACL on the packet capture.

    Destination Zone

    Destination Address
    DMZ Sophos Public Address
    Game_Server_Zone Sophos Public Address
    Game_Server_DMZ Sophos Public Address
    ANY Sophos Public Address

    (Game_Server_Zone is a LAN zone, I created Game_Server_DMZ as a DMZ zone just for testing purposes)

    Is there something somewhere else I may have gotten wrong that I should check?
