update sophos firewalls

We have 4 sophos xg firewall in our internal network. 3 weeks ago we decided to migrate them to 18.5 MR3. after that we couldn't get update from our SFM specially for IPS signature. for more information we can update these module from internet but this part of our network doesn't have internet access.  what can we do about that problem. should we update sfm? any product released instead of sfm?
