hasIpAddress("제 아이피") 허용안됩니다...

Question

안녕하세요 user-service에서 WebSecurity를 작성하고

apigateway에 user-service 정보를 추가하고

- id: user-service
  uri: lb://USER-SERVICE
  predicates:
    - Path=/user-service/login
    - Method=POST
  filters:
    - RemoveRequestHeader=Cookie
    - RewritePath=/user-service/(?<segment>.*), /$\{segment}
- id: user-service
  uri: lb://USER-SERVICE
  predicates:
    - Path=/user-service/users  # 회원가입
    - Method=POST
  filters:
    - RemoveRequestHeader=Cookie
    - RewritePath=/user-service/(?<segment>.*), /$\{segment}
- id: user-service
  uri: lb://USER-SERVICE 
  predicates:
    - Path=/user-service/**
    - Method=GET
  filters:
    - RemoveRequestHeader=Cookie
    - RewritePath=/user-service/(?<segment>.*), /$\{segment}

아래처럼 유레카 서버를 키고 user-service를 클릭했는데 forbbiden 403에러가 뜹니다..

다음은 WebSecurity 코드입니다.

@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

    private UserService userService;
    private BCryptPasswordEncoder bCryptPasswordEncoder;
    private Environment env;

    public WebSecurity(Environment env, UserService userService, BCryptPasswordEncoder bCryptPasswordEncoder){
        this.env = env;
        this.userService = userService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {  // 권한
        http.csrf().disable();
//        http.authorizeRequests().antMatchers("/users/**").permitAll();    // 모든걸 다 허용
        http.authorizeRequests().antMatchers("/**")
                .hasIpAddress("192.168.45.163")// 해당 ip 허용
                .and()
                .addFilter(getAuthenticationFilter());  // 이 필터를 통과하 데이터에 의해서만 허용한다.

        http.headers().frameOptions().disable(); // 프레임별로 데이터가 나눠져있는데 그걸 무시한다.
    }

    private AuthenticationFilter getAuthenticationFilter() throws Exception{
        AuthenticationFilter authenticationFilter = new AuthenticationFilter();
        authenticationFilter.setAuthenticationManager(authenticationManager());

        return authenticationFilter;
    }


    @Override   // 인증 (인증이 되야지만 권한 부여가 가능)
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService).passwordEncoder(bCryptPasswordEncoder);
    }
}

참고로 저는 스프링 부트 2.6.8 버전에 자바 1.8 버전을 사용합니다.

또한 참고로 UserController에 있는 리퀘스트 매핑은 @RequestMapping("/") 상태입니다.

그렇게 유레카 서버에서 user-service를 클릭하면

대략 다음과 같은 에러가 찍힙니다..

검색해도 해결책은 안나오고... 뾰족한 수가 있을까요?
