Hi,
I have a Zywall 2 on ISP 2 with a dynamic IP and I have my Mikrotik at a different ISP on a fix IP. I would like to create a vpn connection between both but I am unable to set it up, lack of competences....

Can anyone help? I am willing to pay for the support as long as I get it working quite fast.

Best regards,
Loic Didelot.

Here are some pointers but it's in Norwegian:

IPsec tunnels must be between two ends with static IPs.
With PPTP your client can have dynamic IP and add a static route for the LAN network on the other end to go through the PPTP tunnel.
I.E :
1 S dst-address=192.168.20.0/24 preferred-source=192.168.98.5 gateway=192.168.20.1 gateway-state=reachable distance=12 interface=VPN

Where 192.168.20.0/24 is the LAN you want to reach, 192.168.98.5 being the IP of your tunnel and 192.168.20.1 the IP of your Pear.

Are we talking VPN as in any VPN or IPSec in specific?

These boxes seem to support IPsec only.
