UTM to UTM RED Connection drops every 3-4 hours

Question

Hi fellow Sophos UTM people. I have a UTM to UTM RED connection setup between two sites where one is my home and the other is a server in a data center. 
 My homes internet connection is passed through the RED interface to the data center UTM, however every 3-4 hours the connection to the RED dies with the following error: 
 
 2017:01:01-21:51:35 home red_client[1173]: CHILD Tunnel 1: Socket was closed 2017:01:01-21:51:35 home red_client[1173]: CHILD Tunnel 1: Unable to read PING response 2017:01:01-21:51:35 home red_client[1173]: Tunnel 1: disconnected 2017:01:01-21:51:38 home red_client[4300]: Tunnel 1: Forking client handler 2017:01:01-21:51:53 home red_client[4217]: CHILD Tunnel 1: performing initial keying. 
 
 While the RED tunnel connects up again within around 15 seconds, this is causing all of my internet to go offline which is starting to get a little annoying during online gaming. 
 Does anyone have any ideas of what i can check? If any more information is required, please let me know. 
 Thanks

I see these restarts at some clients for RED tunnels between two UTMs. I don't know why these occur, but I suspect it's the ISP that's causing the issue. 
 You might consider replacing the RED tunnel with an IPsec or SSL VPN site-to-site.

If the UTM at the Data Center has a Web Filtering subscription, I would use that as a Parent Proxy for those websites in your home configuration instead of worrying about getting specific IPs for the sites in question. If not, then there are ways to route traffic through an IPsec tunnel to solve your problem.
