Sonicwall TZ 105 allow Lan to pull file from DMZ

Have a Sonicwall TZ105 and the client needs to be able to run a batch file on the LAN side that will pull a file from the DMZ side. This is done periodically based on a task on the LAN Side computer.

What is the best way to do this

Thats what I thought.. but its not..

Everything is open from LAN to DMZ and Everything is denied from DMZ to LAN

Is there any NAT setting that has to be applied?

Trying to browse to a computer on that side using \\192.168.11.14\

If I open the DMZ>Lan for all then the DMZ can browse to the lan side

Do you mean you want to access a lan resource from dmz. We can limit the access by selectively allowing any ip for selective services.

NO, From the LAN Side I cannot open the DMZ side

lan is 192.168.68.X

DMZ is 192.168.11.X

Trying to open \\192.168.11.14\ from LAN TO dmz

Oddly if I open everything from DMZ to LAN, then I cna ping and can open \\192.168.68\14\ from the DMZ Side.

Well.. now it decided to start working..

Go figure..

I added an ICMP rule on the DMZ to the LAN to allow, Did a ping, and it worked..
I then turned off the ALLOW all from DMZ to LAn and it still works..

I gues patience plays a part.

Thanks for your help

So the Firewall Access rule from LAN to DMZ is allowed but you can not initiatate a connection from lan to dmz, is that what you experiancing. Please allow the required type of services from lan to dmz if its not already there.

Return traffic from dmz to lan will be allowed.

Miftaul H

The log shows you are initiating the connection from dmz to lan, where it should've been the other way, init.

Good that it works. Thanks.

I am fairly sure it was a windows firewall issue on the DMZ Side
