IBKR-incoming-connection-attempt-prompt

Really it's a question for IB since it's the option will be somewhere in the TWS API configuration. I looked, but honestly I can't put my finger on one that sounds like it would do the trick. :/

Here you go... from the IB API Doc (https://ibkrcampus.com/campus/ibkr-api-page/twsapi-doc/#tws-config-api) ...

QUOTE:
In TWS, if you don’ t put the remote IP Address into the “Trusted IPs” and you try to establish remote API connection, there will be a message “Accept incoming connection attempt from <IP Address>” which requires you to accept the connection or reject the connection. In IB Gateway, it is compulsory for IB Gateway users to put the remote IP Address into the “Trusted IPs”. Otherwise, there will be no connection attempt detected.

Tks.
