AVM-portfw⚓︎

• Package: master/make/pkgs/avm-portfw/
• Steward: @fda77

AVM-portfw can expose ports of the Fritz!Box itself, and only those ports, for access from the internet.

It uses internet_forwardrules and only supports IPv4 forwards. It can be found in menuconfig under packages > webif.
Because ar7.cfg is modified, create a complete backup first - EXPERIMENTAL!

• Specify port blocks as PORT+COUNT, for example 55500+3 for 55500-55502.
• Specify redirects as EXTERNAL(+COUNT):INTERNAL, for example 443:8443 or 80+2:8008.
• The entries can be checked in the AVM web interface under Diagnosis > Security.
• If there are syntax errors, AVM resets the complete ar7.cfg.
