Hi guys,

I have a modem (Technicolor TG582n) that doesn't allow to block ips via a browser interface.
I have tried doing the task via telnet following this guide: http://phil.tinsleyviaduct.com/tg582nfirewall.html

:expr add name=blockedips type=ip addr=xxx.xxx.xx.xxx
:firewall rule add chain=forward_level_Normal index=2 srcintf=wan srcip=blockedips action=drop

In the past I have managed to complete the task following the guide but when the modem has to be reset I need to rewrite the rules.

The problem I am facing is that I cannot complete the command since I get this error:

Error: Unknown error.
Bad value for parameter 'chain forward_level_Normal'


Through the command ":expr list" I can see the blocked addresses but not the firewall rule.
I don't know what I am doing wrong so i hope someone could provide some help.

Many thanks. :)
