I am new to Zentyal, but this seems like should be easy. Could someone give me step by step to opening rdp, i want to forward from 3395 to 3389 and allow rdp services. I have setup custom service for rdp, set a range of ports for it of 3389-3400 so that i can redirect more ports later. I have messed with various packet filter rules, always deleting them if they don't work. I guess i am missing something easy and just need someone to guide through the process.
