I'm hoping someone can point me in the right direction, or at least help me track down the problem.
I'm using a TZ210 to connect to a clients network. Previously i was using the mobile vpn solution which works but not all the time, so i got a sonic wall in to get around this.
They have other offices that are using sonic wall successfully.
We have set up the connection and the tunnel is up and running
However i don't get traffic across it. I can see in the tunnel overview that packets are being sent too the VPN but there's no traffic back. I can see in the logs that i get a TCP Connection reject received; TCP Connection Dropped, from the destination IP to my network.
In the VPN settings i have my network locally which is 192.168.2.x and two networks remotely, one is a network 172.16.12.0 (subnet 255.255.254.0) / and one is a range192.168.200.0 -> 192.168.201.255
The tunnel is up though.
I've tried selecting the remote address group as WAN and VPN but the same issue
The firewall seems to be set to allow traffic in and out of the VPN.
What can i do to troubleshoot this as i'm stuck now.
