I am using Sophos XG115 as the firewall and i do have a layer 3 switch (Unifi 8 port POE 60W switch) which leverages VLANS created & tagged at XG115.
Users in different VLANs want to connect to devices (e.g. Network Printer and Network Attached Storage device [TerraMaster]) located in another VLAN.
i have created a firewall rule which enables the communication between VLANS. I have also created DHCP records for each VLANs at XG115.
I am able to PING to the gateway addresses of each VLAN. Unfortunately, the trace route keeps on failing at the gateway address of LAN network port at XG11 5when trying to reach to devices in different VLANs.
Can someone help me in steps on what we should be adding or enabling to allow users in different VLANs to access the NAS and Printer?
Please note that users are on stand-alone Windows 10 devices. There is no active directory or LDAP integrations (i mean there is no Windows server).
Below is a diagram of the network. An early response is highly appreciated.
Hello, try source zone :lan , source network select all VLAN inside and the same for destination zone: LAN and destination network : all VLAN . move the rule set to the top position at the Intranet rulesets…
UJay In this scenario, you need to add static route in the firewall. For an IPv4 unicast route, go to Configure > Routing > Static Routing and click Add under IPv4 Unicast Route.https://docs.sophos.com/nsg/sophos-firewall/v17.1.4/Help/en-us/webhelp/onlinehelp/index.html#page/onlinehelp%2FUnicastRouteEdit.html%23Video link: https://www.youtube.com/watch?v=h-nu7tMfL_E
Hope this helps!

I tried your suggestion and still unable to cross from one VLAN to another.
I am able to ping between gateways of each VLANs but not able to trace route or ping a specific IP address of device.
Do you forward all VLAN's to the XG or terminates the L3-Switch the VLAN and use a transfer-subnet to communicate with XG?
... where is the gefault gateway-IP for the VLAN's located .. at the Switch or at the XG?
If XG is the gateway - you don't need additional routes.
Would be helpful you post a screenshot of XG - interfaces-list.
and follow the suggestion from rfcat_vk:
" On the first rule try changing the any to LAN and enable logging so you can see what if any traffic is attempting to use the firewall rule. Also please make it the top of the rule list."
check the log-viewer...
BTW: are your clients able to access the internet?

... and a common error: check the IP/subnet-mask and gateway at the NAS!!
with regard to common error - yes i have checked those. Also to make troubleshooting easy, i am using a PC on the VLAN 4 so I can try tracert, ping, and other network troubleshooting commands from both ends to whether it is only dropped at one end or both.
- you are able to access the internet from all VLAN's (or at least the two that should communicate one with the other)
- do you see this traffic within logviewer/firewall? ... enabe logging for all rules for testing.
- try to access the NAS within other VLAN (not with HTTP ... this may be handled different) ... do you see allowed or blocked packets within logviewer?
- try to ping NAS & Printer ... something within logviewer?
- please show us the VLAN's behind Port1

Yes i am able to access Internet from all VLANs, there is no issue. I was using these VLANs and users were accessing Internet from May 2021.
When do a ping or tracert to NAS via 2 different VLANs they dont get logged in the logviewer.
Accessing of the NAS is not web based (not HTTP). I use the \\NASipaddress\ to access it.
PING to the NAS IP address fails.
Hope the above helps to clear some doubts at your end
Can you ping the nas from its network?ian
Yes I can PING the NAS from the VLAN where it is located. Then i can PING and TRACER the gateway IP of the VLAN where NAS is located from any other VLANs. But the PING or TRACERT to the NAS from other VLANs fails.
So what happens when you try to access other devices on the NAS VLAN?
The other device on this VLAN is the printer. It is using TCP/IP port configuration, hence printing can be done without any issues.
Okay, what is the nas using, sounds like it has a firewall enabled blocking incoming traffic on specific ports?
