softether Layer3 routing between virtual hubs

straightforward scenario but I've spent hours on this without success I have one server with 2 virtual hubs configured with secureNAT enabled and DHCP set with the below

virtual hub1
192.168.30.1 - 192.168.50.200

virtual hub2
192.168.100.30 - 192.168.100.200

I want to route between the 2 hubs using the Layer3 switch that I have configured with the below settings for the virtual interface

192.168.1.50.201 / 255.255.0.0 
192.168.100.201 / 255.255.0.0 

the L3 switch is started and online

From virtual hub1 I can ping 192.168.50.201 all fine from virtual hub 2 I cannot ping 192.168.100.201 ???

I can see the interfaces created in the IP tables section on both hubs - see attachments End goal is cross communication between hubs.

please any advice appreciated - this really seems quite forward without success

Solution 1:

If you have mask 255.255.0.0 i.e. 192.168.30.1/16 it covers range from 192.168.0.0 to 192.168.255.255. Therefore, it's looking for 192.168.100.201 on the same subnet i.e. using only layer 2 without any routing.

For routing, you need to use subnets that won't overlap. If you wish to continue using these ranges, that would be:

• 192.168.0.0/18 from 192.168.0.0 to 192.168.63.255 (mask 255.255.192.0 with 16384 hosts)
• 192.168.100.0/24 from 192.168.100.0 to 192.168.100.255 (mask 255.255.255.0 with 256 hosts)

After learning the basics on IPv4 subnetting you'd choose better IP ranges according to your needs for the amount of hosts on the same subnet.
