BIP IP Edge Client - Network Access - Can't reach client from internal network.

Hello everybody,

We do SSL VPN through a BIg ip f5 with the big ip edge client. The IP range distributed to the client is 10.227.4.0/22 ​​using a network access configuration in full tunneling. The client connects properly and there is no problem getting a resource internally attached. However it is impossible to reach the customer from the internal network. Is it possible to join the customer for maintenance or does the principle of reverse proxy prevent it?

Thanks in advance
