Hello there!
Please, help me to maintain site-to-site VPN network between head office and branches of my company! In the head office i have Windows Server 2003 R2 with ISA Server 2006 installed. My task is to choose hardware router for the branches. What actual zyxel products are compatible with ISA Server 2006 and are there step-by-step instructions how to configure site-to-site VPN with ISA Server?

Thanks in advance for any suggestions!

    Hi @komsomolec  

    We have no ISA server of it, but there is noproblem to establishing VPN tunnel.

    First you can follow Window wizard to creating the configuration on your ISA server: 

    (1)   IPSec tunnel mode.

    (2)   Creating VPN gateway IP. (WAN IP address of ISA and USG WAN interface)

    (3)   Pre-shared key

    (4)   Create remote side subnet.  (IP subnet on USG)

    (5)   Create local side subnet and routing.

    After created the rule you can change phase 1 and phase 2 algorism on ISA server.

    On USG there are same configuratino for VPN tunnel.

    VPN gateway (Phase 1):

    VPN connection (Phase 2)
