Good afternoon,
I tried to create a VPN between a USG 310 with firmware 4.33    and a USG 300 with firmware 3.30 (2015 the last one available for USG 300) , follwing your instruction about VPN - Setup Wizard   -  SIte to Site with  public static IP for both the  Zyxell USGs.    
But when I try to connect , I get always a massage  of  Dial IN Time Out.   
Is it possibile to connect  via  VPN  USG 310 and 300    or thereis a firmaware upgrade problemm  (different realease of firmware)   ?  
Thanks in advance for your help

    IMVHO should be possible, only you have to doublecheck every settings into gateway and tunnel section.
    I'm using USG60 (4.35) to connect via IPSec to USG20 (3.30), USG20-VPN (4.35), USG40 (4.35).
    And USG40 (4.35) to USG20 (3.30)
    Anyway: be sure to have the latest firmware available for every device.

    Hi. This is possible. We have many USG1000 connected to USG1100.
    First, check in log ike section during ipsec tries to connect. If you see error like "no proposal chosen" - this is differents in vpn configs. USG310 must be in IKEv1.
    Than check phase settings in advanced settings.

    They must be the same on both sides in vpn gw & vpn connections settings. By default, v3.30 has more less settings.
    And finally, check that 1 ZW has access to another by ipsec ports.
