I use a programme which i have not been able to use for quite some time. Their tech helpdesk told me that port Nos. 443, 49498 & 41599 are required to run the programme and that to ask my administrator to open all these ports for incoming and outgoing connection in firewall and also in proxy server if any used in my office. When contacted the administrator said all ports are open. What do i do? How do i check whether these ports are open / blocked and if blocked how do i open them?
