Hello
I recently upgraded my Sophos XG 2300 to SFOS v20 which is in Head Office, where I am running site to site vpn: IPsec tunnels to 6 branch offices and IPsec Profile is set to Head Office, policy based for all IPsec Tunnels on Head Office firewall.
Branch Office firewall range from XG 2100 to 135. IPsec tunnels are set Branch Office profiles. I haven't changed any configurations
I have noticed that recently in different sites randomly, one Vlan network on a IPsec Tunnel will just stop communicating to head office firewall, the tunnel doesn't drop at all, but if I disconnect re-connect IPsec Tunnel that Vlan network will start to work again.
How can I over come this or try to root down this problem, this has happened to all the branche office firewall randomly.
