VPN - Site to Ste (Sonicwall & Zyxel)

Hi there,

I have a Sonicwall NSA firewall in my headoffice. I also have a branch office that I want to connect using site-to-site VPN.

I have a Zyxel router in the branch and I am wondering if I can connect the zyxel to the sonicwall with a site-to-site VPN tunnel.

If it is possible, I am looking for instructions on how to do it.

Thanks in advance

What model number of Zyxel? I believe the majority of the ISP routers will only pass VPN connections not make them. You may need another firewall/VPN device on the inside of your Zxyel router and forward the ports to that device.


I managed to resolved the problem. I found an article on the web.

Thanks again
