I am in the process of setting up my IB account. I just downloaded my the stand alone TWS. I use Zone Alarms free edition(3.1.395) firewall. My question is: In step 9 of TWS set-up, it asks you: What should I enter in this field? I am not very computer savvy, but I thought a firewall and a restricted router were different things. Any help, would be much appreciated.
