Failed to parse group `firewall` on SAGECOM F@ST 3686v2 - Vodafone #30

I happen to have a Sagecom F@ST 3686v2, and its GatewaySettings.bin is perfectly read by bcm2-utils, except for the firewall sections:

I can send my .bin file if it helps.

Thanks and thanks for this tool, I have been able to adjust several parameters of my router that my company blocks us for no apparent reason.

I also have this issue. My router is an Arris SBG6580-2.

There are very different formats for the firewall group. Unless you've got access to the firmware console (via serial port or telnet), there's really no way I can implement this. Also COVID keeps me quite busy at the moment.

Hi @jclehner

I can't get access to telnet, even trying to change the configuration from the GatewaySettings.bin but I do get access via SSH
