some basic questions about sophos live connect and software firewall

hello everyone

i have 3 question

i just installed new astaro gateway 9 and upgrade my home license

please anyone tell ........ do i need a software firewall with astaro endpoint as well because i didnt see firewall option on software side

2nd i restore my setttings from 8.305 but now i made screenshot/write all my settings and start with factory setting again and set again.

now do i need to reinstall spohos endipoint as well on software client side as well or same will work.

3rd question how to set sophos live connect i used to use norton DNS in which what i do is disable DNS to out in firewall setting ....... set astaro as DNS(dhcp on) and add norton DNS in forwarder setting instead of my ISP

now i cannot able to set sophos live connect in forwarder setting please what i am doing wrong


thanks for help in advance
