One of our client wants to do port forwarding to the crm server , so that users can access the crm from Internet. They are using ZyXel firewall (for port forwarding).
They have mapped 203.xx.xx.xx(public ip) to 192.Xx.xx.xx(local ip) with incoming and outgoing port 5555(default port of our crm server), but it doesn't work. Any suggestions?
I tried to map for rdp and sql report server(web server), these things are able to access.
I have been stuck with this more than a day. Can anyone please help
