which one to choose?

DR_SERVIZI

could you give me a hand for a quote to do for a customer relating to a firewall that performs the following functions:

- 2 separate LAN IPs (LAN1 x OFFICE SWITCH 192.x.x.x and LAN2 x GUEST SWITCH 122.x.x.x)
- 2 WAN with load balancing or bonding and failover backup operation (WAN1 x FIBRA ESTRA proprietary router not modifiable and WAN2 x FIBRA TIM proprietary router not modifiable)
- Optional VPN in case it is to be implemented at a later time (perhaps with a setup program to be sent to the external client PC to make the connection ready by installing it)

Hi @DR_SERVIZI

Welcome to Zyxel community. According to your requirement, we suggest you could choose UGG Flex 200/500/700 or ATP 200/500/800  models and you can refer to this (Where to Buy) link to see which channel you can contact to purchase our product. Thanks .

Or VPN100/300 unless they EOL before Flex/ATP?

Personal opinion...
Also USG Flex 100 allows three "internal" LAN ports + 2 WAN ports (one is configurable and is on port 5) for allowing the same configuration. Less bandwidth among Ports/lan segments, but anyway can fit the challenge.
Unless one or both WAN connections allows more than 500mbps each. Therefore, maybe USG 100 Flex might be on the short side.
