VPN Tunnel ZyXEL USG 300 & Draytek Vigor 2820

Posted on 2012-08-31

Hi guys,

Some chaps have been in to one of our clients and configured a wireless system and put in their own firewall.

I did mention there was a VPN tunnel via two Draytek Vigor 2820 routers, they said this would be fine but they've managed to screw it.

I've had a play with the ZyXEL USG 300 VPN configuration and the Vigor 2820 VPN configuration but I can't get it to play ball.

I know this is a longshot but does anyone know if a VPN tunnel between these two devices is possible?

Many thanks in advance.

    Did you verify that both sides support the same set of parameters.
    [ encryption type, timeout values ... etc. ]

    How to answer if there quite some lack of information...
    The first thing is to check if there is discrepancy in settings. none are presented here.

    I am prepared to cary this further if more info is supplied about settings [ no secrets, no public ip's etc. ]

    Sorry I didn't mean to come across dismissive, we managed to resolve this ourselves in the end.

    The ZyXEL router seemed to make a lot of assumptions in terms of authentication and encryption. It look a lot of messing around but we eventually managed to get it to work, although it's not very secure.

    We're now awaiting MPLS as we have leased lines going in.

    Apologies for wasting time and not following this up.
