Hi Please can someone advise on what I need to do to input the Firewall settings so I can install Acronis True Image? Do I set up port forwarding on our router and assign the ports the IP addresses detailed below? Also, Where do I put the multicast addresses? This is the bit I'm not sure about. 2.2.2 Firewall setup Acronis True Image for Microsoft Small Business Server uses the following ports and IP addresses for remote operation: server (Acronis True Image Agent) UDP port: 9876 server (Acronis True Image Agent) TCP port: 9876, if busy choose a port at random client (Acronis True Image Management Console) UDP port: 9877, if busy choose a port at random IPv4 multicast address: 220.127.116.11 IPv6 multicast address: FF05::fAA5:741E. Please help!
