I have sbs 2003 premium technologies. My server has two NICs and I used ISA as a firewall to connect to the internet. Now, I have moved to SonicWALL UTM device. I have disabled second NIC and uninstalled ISA. I have run CEICW Wizard too. It says it can not configure the firewall that comes with SBS as there is no second NIC and I have to configure external firewall. Fine, my sonicwall tz210 is online.
Now, there is no firewall running on the server. What should I do to protect it from attacks from the inside of the LAN? Is it not possible to turn on windows firewall? Is it safe not to have any firewall at all on the server?
