I am trying to connect two sites using a VPN between two SonicWALL appliances. The central site is using SonicWALL TZ 200, and the remote site is using a TZ 170. The central site has 13 users, and the remote site has 3 users. The VPN connection gets established. I can ping between the sites, and I can connect to the shared network resources. My problem is that the remote site cannot browse the internet. I am using Internet Explorer 8 on two of the three computers at the remote site and IE9 on the third. For a few minutes,
I am using the Comcast cable modem at the remote site as a bridge, with DHCP being provided by the TZ 200 at the central site.
In the log at the central site, I see errors that UDP connection dropped, then a few that say ICMP Packet dropped, and then TCP connection dropped. On the computers at the remote site, when I run the troubleshooter on the network connection, if it says anything, it will say that the DNS server is not responding. The DNS servers are assigned by the central TZ 200. Computers at the central site have no problem connecting to the internet.
I used the setup at this link: http://www.sonicwall.com/downloads/Site_to_Site_VPN_Using_DHCP_over_VPn__SonicOS_Enhanced_at__.pdf
Any ideas on how to get the remote sites connected to the internet?
