成员提供程序返回remoteAddress为空

我们使用专有的单点登录服务远程执行会员呼叫。我们通过VPN连接。

我们得到一个错误:

Service.Web.Security.Membership.ValidateUser(username, password);

无论VPN是否工作:

Web的相关区域。配置:

                </binding>
            </netTcpBinding>
        </bindings>
<client>
            <endpoint address=""
                binding="netTcpBinding" bindingConfiguration="Membership_NetTcpBinding"
                contract="MembershipProviderService.MembershipService" name="Membership_NetTcpBinding" >
            </endpoint>
</client>

我们可以通过ConnectionStringToRemoteDB1中的凭据远程访问DB。我们被告知MembershipProviderService。MembershipService'和相关的api被设计为从数据库获取远程地址，并将其提供给成员资格提供者。

有没有人看到任何问题的配置在这里尖叫，这将无法工作?这感觉就像缺少了一个配置块，但是通过VPN跨域消费服务使得很难知道问题可能是什么。谢谢你的建议!
