Hide gateway IP

General

Good day, everyone!

When i set keep_private_host = true in janus.jcfg my remote candidate looks like this

candidate:1 1 udp 2013266431 91.198.xx.xx 51739 typ host  < Public IP
candidate:1 1 udp 2013266431 10.1.96.1 51739 typ host     < Gateway IP
candidate:1 1 udp 2013266431 10.1.96.50 51739 typ host    < Local IP

Then i set keep_private_host = false, Local IP is gone, but Gateway IP still present.
for example

candidate:1 1 udp 2013266431 91.198.xx.xx 51739 typ host  < Public IP
candidate:1 1 udp 2013266431 10.1.96.1 51739 typ host     < Gateway IP

It is possible hide gateway IP?
And leave only Public IP in remote candidates?

Best regards, Vitaliy.
