    I modified the port to 843 and add the security policy(Wan->lan, Source: my IP address, allow)
    I can access device via SSL VPN(Enter public with port:843)

    As you mentioned, did you test wan1 public IP with port 843  successfully via SSL VPN?
    Please check rules if you disable the firewall and issue disappear.
