Hey VPN experts
We have three offices which are connected via VPN.
Headoffice - Netgear SRX 5308 firewall
Branch Office 1 - Netgear SRX 5308 firewall
Branch Office 2 - Netgear SRXN3205 firewall
The VPN between HO and BO1 is fine.
The VPN between HO and BO2 is not fine.
Just the VPN itself is generating excessive traffic.
Especially the upload from BO2 is showing very high amount in very small space of time.
I know its the VPN because I have disconnected any local devices from both firewall for good 10 minutes so both firewalls has only the Internet connection and the VPN between HO and BO2 (BO1 vpn was also disconnected).
The VPN configuration is just the standard configuration for most part when you create an IKE VPN policy on both ends. I have just added a PSK which is just a simple password for VPN connection.
This excessive traffic is taking up most of the bandwidth at BO2 and the users are struggling.
Any help would be really appreciated.
