Need help on connection to brokers

 
I am having problems to connect to any brokers at work after they said they had updated their infrastructure. I tried two different laptops to connect brokers but none of them worked. When I am at home and use home internet, there is no any problem to connect to any brokers. It tells me that the root cause is the firewall at work. I am looking for help to solve it.
