RV340 Disabling Inter-VLAN Routing makes http server not accessible from internal computers in the same vlan

[swu2019]

I have two VLANs on RV340 router. One VLAN is for all computers include server. Another VLAN is for WiFi devices. Both of them are truned off Inter-VLAN Routing in order to separate them.

The problem is that computers cannot access a HTTP server in the same VLAN. But external computers outside of the router can access the HTTP server. Enabling computers' VLAN Inter-VLAN Routing makes the access working. 

I don't understand the definition of "Inter-VLAN Routing".

Any input is appreciated.

Thank you.

Inter-VLAN routing routes packets from one VLAN to the another VLAN.  Question,  Did you assign a network to each VLAN?  Outside makes no sense unless you are talking about outside the firewall which should not have anything to do with your inside the firewall VLAN routing.  Outside is firewalled, hopefully.

Yes. Two VLANs have their subnets as 192.168.2.X and 192.168.10.X. Port forwarding and access control rules are enabled.

Just basic question to ask ?

what is the Device here ?

what is the Version running ?

what is your current config ? what is the VLAN which has servers, what is the VLAN the device connected which can not access to SERVER ?

The router is RV340 and its firmware is the latest version.

Hi @swu2019 ,

In addition to what has already been requested, I believe that a diagram of your network would be useful.
