I need to configure a firewall (ZyXEL ZyWALL USG 100) to permit traffic split between two connections for Internet.
In one connection I should direct traffic to a server farm that contains business applications, this WAN has a private netowork address with 10.x.x.x/255.255.255.0 range, always on this connection is redirect VoIP traffic, which is not controlled by firewall, and emails business ( POP3 and SMTP).
On the other line the entire web browsing.
What might be the optimal configuration?
I would also like to make it possible to handle two lines in backup mode one to another.
I attach a pdf file with the design of network infrastructure.
