I have created a VPN between a Sonicwall NSA 240 and a Draytek Vigo 2830

The LAN network IP for the Sonicwall is 192.168.58.0/24
The LAN network Ip for the Draytek is 192.168.56.0/24

From PCs on the Sonicwall LAN I can access the Draytek router's web page (192.168.56.1)
But cannot access any servers/workstations on the LAN.

The server has it's firewalls turned off.
Any suggestions on what the issue is?

Can you ping any thing on the other side?

Sounds like you need to open ports back to the server ip address.

It sounds like the pcs and servers on the other side are using a different router as thier default gateway, if this is the case you need to add a static route on that gateway pointing to the subnet 192.168.56.0.

A tracert from the pc's on 192.168.56.0 will verify if this is the problem.

The server and PCs on the branch office cannot ping anything at the head office. Not even the gateway router.

I have opened the ports to the server on the router.
I have port forwarded 3389 (RDP)

It still doesn't ping, RDP doesn't work.
Cannot access any resources either side of the network.
ie... PCs on 192.168.58.0/24 cannot access any PCs on 192.168.56.0/24 accept the router on 192.168.56.1
PCs on 192.168.56.0/24 cannot access any PCs on 192.168.58.0/24

Obviously the tracert will fail but I want to see the path.

A vlan on the draytek was causing the problem, and reconfiguring the vlan  resolved the issue.

Thanks for your time.
