Proxy Server Publish Issue

Based on Mesh SDK 2.1.1.

I use light switch proxy client & proxy server to test server publish function.

But when I use the phone setting network, I found that the client's publish & subscribe settings, the server's publish function can be used correctly.

If the client only sets subscribe and doesn't set publish,the server's publish function can't be used.

Can I set the client's subscribe and server's publish separately to use the publish function?

client set publish & subscribeclient only set subscribe

right figure : client only set subscribe

Server set publish
