Hello,
I'm new to Sophos, and am deploying my first firewall to a very basic client, and just want to check what I have configured is a reasonable balance between security and functionality? I am just looking for opinions and whether I have missed anything major? I do understand setting security can be like measuring the length of string so to speak.
Note as I don't want to risk too many problems I have just allowed everything LAN to LAN.
Also note I have a disabled 'deny LAN and WiFi to Internet' rule at the top so it can quickly be isolated in case of attack.
The allowed services for access to the web are;
DNS, FTP, HTTP, HTTPS, ICMP, ICMPv6, NTP, SIP, SIP-MSNmessenger, SNMP
