Sonicwall site to site VPN, no access to remote network

Some info for the below scenario.

Site A - 192.168.25.0/24
Site B - 192.168.45.0/24

Sonicwall at Site A - 192.168.25.1
Sonicwall at Site B - 192.168.45.1

I have a site to site VPN active between two remote locations. The VPN is established fine. People at site B can access the server at site A. I log on to the server (192.168.25.5) at site A and I try to go to the web management page for the Sonciwall at site B and I cannot acess. I CAN ping 192.168.45.1 from the server with no issue. I also want to access a network Buffalo drive which is at Site B. The address is 192.168.45.10. I want to access this from the server at Site A (192.168.25.1) and I cannot do so.

Again, people at site B CAN access servers and data at site A. As far as I know everything on both Sonicwalls are set the same.

Does anyone have any thoughts?

At site B is there an "access list" that allows the site A subnet range to access site B.

At site B there is a firewall rule that is allowing all traffic from the A subnet range to access site B.

tolinrome

is that firewall rule allowing https? Can you post the configuration from both firewalls for comparison?

Carl Dula

When configuring the STS VPN did you remember to define the network access at Site B on the VPN config, Network tab, similar to what you did on the Site A Sonicwall.

Here are the specific settings on both Sonciwalls. Unfortunately I cannot download the config to a file like on a Cisco device.

Site A (main office with the file server)
VPN Zone is set to Allow Interface Trust

VPN Settings > Network Page

I think that is all of the settings that are pertinant. Most of the firewall rules are created when the VPN is created and cannot be edited. So again, SiteB can access data at SiteA but not the other way around.

Thanks!

"You have to enable Management on the VA on the applicable Zone."

I do not see how to enable Management on the zone. Management can only be enabled on the interface, and that is either LAN or WAN. If enabled on the LAN zone, I should be able to use it through the VPN. I could live without this if only I could access data on SiteB from SiteA.
