You're quite welcome. Great to hear. It's strange how many products have advertised features that don't really work, and then once the firmware is updated, start working great.

I have a VPN link between two locations and have been using the old ZyWall 2+. Has worked well. Need to replace one of the routers with a ZyXEL USG 20, and I'm not able to get the two boxes to even set up the tunnel. Have checed the settings over and over, but not found what is wrong.

Tried to figure out what is going on from the logs, but don't understand all of it. Have attached screenshots of logs at both sides in case it may help. Any suggestions how to get this up and working??<br />

I have a VPN link between two locations and have been using the old ZyWall 2+. Has worked well. Need to replace one of the routers with a ZyXEL USG 20, and I'm not able to get the two boxes to even set up the tunnel. Have checed the settings over and over, but not found what is wrong. Also wen through the article at ftp://ftp.zyxel.com/ZyWALL.../ZyWALL%20USG%2020_2.pdf  and did all the settings according to this, but still no tunnel or connection between the boxes.
Tried to figure out what is going on from the logs, but don't understand all of it. Have attached screenshots of logs at both sides in case it may help. Any suggestions how to get this up and working??

Setting up ipSec VPN between ZyXEL routers

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
