Firewall disabled, is it sure?

[lwizard]

Is it sure to disable firewall?
If I do so firewall-start script does work or no? (I use it to open ports for torrent).

It seems that latest Merlin (.50) has a bug because firewall block my ip camera only when accessed from the LAN through WAN address (LAN>WAN>LAN).
Restarting the firewall after first boot fix it and also disabling the firewall.
So I think it's better disabling...

Do not disable the firewall. It opens your ENTIRE LAN to the Internet, and will also break a lot of features in the router that rely on firewall rules.

Thanks.
I will re-enable right now Port forwarding of transmission was working through firewall-start script even if firewall was disabled. Are you sure that disabling it through the web interface does disable entire firewall? It seems that port forwarding and firewall-start was working right.. maybe the firewall does not disable but apply more permitting rules??

Also there is an incoerence in URL filter. If I disable firewall URL filter is cleared, but if I add something in URL filter with firewall disabled, the url is filtered and firewall still disabled!

Merlin can you imagine why my ipcam is not accessible from LAN>WAN>LAN (but is accessible from LAN and WAN) untill firewall is restarted after first boot?
I also had a temporary internet hangs yesterday which solved in few minutes.
Does this mean anything:
Feb 21 11:43:34 dnsmasq[15513]: warning: interface ppp1* does not currently exist
?

Thanks!
