My liferay portlet jsonws not accessible from remote location but i can access it using localhost

```
example [http://localhost:8050/MySite-portlet/api/secure/jsonws] is accesible on the lacal machine
but when i try to access it remotely using the external ip e.g
[http://120.23.223.24:8050/MySite-portlet/api/secure/jsonws] its returning me the Connection refused error

```

However `[http://120.23.223.24:8050/api/jsonws]` and `[http://120.23.223.24:8050/web/MySite]` is working

my portal-ext.properties file contains the following entries

```
open.id.auth.enabled=
auth.login.site.url=
auth.login.community.url=
company.default.home.url=
default.logout.page.path=
default.landing.page.path=
redirect.url.ips.allowed=
jsonws.servlet.hosts.allowed=
json.servlet.hosts.allowed=
json.web.service.enabled=true
jsonws.web.service.public.methods=*
json.service.auth.token.enabled=true
jsonws.web.service.strict.http.method=false

```

I am using liferay-tomcat 6.1.0

Below is the error I am getting
