AVM offers a friendly user interface with Fritz!OS for their Fritz!Box’es to unleash a nice range of features. Many things are possible, though some things take quite a few clicks.<\/p>\n\n\n\n
One of the things that take many clicks, is arranging port fortwarding for hosts on the LAN. <\/p>\n\n\n\n
The easiest way, after a fashion, is to make a backup of the configuration, make changes and import the file again. The difficulty here is that the file is checksummed, and Fritz refuses to read the configuration. <\/p>\n\n\n\n
While the ages, solutions have been written in various languages. I use a python script, fritzchecksum, written by Mementum\/DRe<\/a>. <\/p>\n\n\n\n It is an pip-installable module, For future reference, the zip contains the current download from github. Should not be necessary to download it here, but you never know!<\/p>\npip install fritzchecksum<\/code>, takes a Fritz-file as input and returns the old and new checksum for easy search and replace. The program supports automatic editing of the file as well, I have always replaced by hand. <\/p>\n\n\n\n
