Inter VLAN to different Subnet

Product Discussion

I am trying to setup a VLAN on one port to allow easy access to reconfigure new devices on their default IP address of 10.90.90.90.
Setup VLAN 10 is configured as follows:

Inter-VLAN is checked for both MainNetwork/VLAN None and Setup/VLAN 10.
An explicit Router Internal Firewall Rule is Enabled for any protocol from 192.168.34.9/24 to 10.90.90.89/8
From the System > Setup tab on the Surf SoHo Mk3 with Firmware 8.3.0, the ping to LAN Setup > 10.90.90.90 is successful.
From a Windows 10 machine on 192.168.34.9/24, with Windows Firewall turned off, pinging 10.90.90.90 is unsuccessful.
What am I missing, or what can I do to troubleshoot?

And the same lack of ping from my Macbook

When devices are configured with a default IP they expect another device on the same subnet to try and access them so they don’t typically have a default gateway set (ie 10.90.90.89 in your example) to allow them to reply to devices in other subnets.

Use virtual network mapping to setup a virtual local subnet you can hit from your management VLAN that maps to the 10.90.90.89 IP (don’t use the /8 its too big. Use /24 instead) eg:

Then you can access that default IP of 10.90.90.90 using 10.100.100.90 (in this example).

You can even do this over a VPN which is VERY useful when you need to factory reset some dumb device and get access to it remotely to reconfigure it.

Thanks!!! (And Virtual Network mapping was well hidden under the “?” icon for Static Route Settings.)
