We have 3 x Endian Firewalls setup in 3 different locations.
One has a fixed IP, the other 2 run DynDns
We need to create a VPN between the firewalls to allow for internal network traffic, mainly prioritizing VOIP traffic.
The firewalls are already in place, we just need the VPN setup and working, and ensure that existing firewall rules are secure.
Remote access to the firewalls is in place via Teamviewer.
We would prefer someone who has experience in Endian firewall with VPN, but all proposals will be considered.
