Connect 2 LANs VPN Server - VPN bridge question

[dimb]

Hi all,
I am very new to Softether VPN, I have tried to install it on a working environment and have some problems on things that I cannot find out how to implement, so please your help is highly appreciated.
Let me explain :
I want to connect 2 LANs over internet.
LAN-A is 192.168.0.x and LAN-B is 192.168.2.x.
LAN-A uses an internet static IP.
I choose a PC on LAN-A and install Softether VPN server. I add one user.
I choose a PC on LAN-B and install Softether VPN bridge. I configure it to connect to VPN server on LAN-A and it connects fine, reporting connection established.

And then what ? How the other PCs from LAN-B can see the other PCs from LAN-A and vice versa ?
Also, when I ping from the PC set as bridge in LAN-B to the PC set as server in LAN-A, it does not respond.

Please note that If I use Softether VPN client to connect to the VPN server it connects fine and also works fine.

Thank you in advance.

Because LAN A and LAN B segment are different.
I suggest doing these steps.
1. Set DHCP servers to lease same subnet but IP address ranges that do not overlap.
2. Filter the DHCP packet by security policy.

Thank you for replying.
I cannot understand why it has to do with DHCP, since subnets have different segments and DHCP server on each LAN takes care only for local LAN's computers. I mean, the 2 DHCP servers cannot overlap in such a configuration, am I right ? They are already preconfigured one to give addresses e.g. from 192.168.0.100-0.150 and the other from 192.168.2.100-2.150. Is overlap possible ?
While searching and reading in order to achieve something similar using OpenVPN, I read that routers have also to be configured with static routes: Each LAN's router has to be configured with a static route to the other network.

But this again did not succeed.

Please try to explain or give a step by step guide, because I have been trying many days for this but without success.
Thank you very much.

SoftEther VPN emulates Ethernet.
Naturally, a host can't communicate across different subnet.

You should set DHCP servers to lease "same subnet" but IP address ranges that do not overlap.

Thank you again, but I still don't get it.
Suppose that I don't use DHCP on my 2 subnets all local IP addresses are static, then what ?
What is the configuration that I must have so that a PC with a static IP e.g. 192.168.0.50 can ping and contact to a PC of the other subnet with static IP e.g. 192.168.2.70 ?
Is there some step-by-step example to study ?

[thisjun]

Please use same subnet for both.
A host can't communicate with different subnet host without router.

I cannot have the same subnet in both LANS (that cannot change) and there IS a router.
Each side uses a common modem/router to connect to Internet.

Maybe some static routes have to be configured on each router so that when a device from LAN-A calls an IP of LAN-B's subnet then LAN-A's router knows where to send such packet (and vice-versa) ?

All this time (almost 1 month) I have been trying to achieve what I asked in the beginning but I could not.
On the other hand, I managed very easily to create a VPN server and use VPN client to connect to it - and it works great. It would also be much more great if the first subject could be achieved - to connect to LANs.
Please is there some step-by-step guide or could someone post a short guide on how to di it ?
It's a pity to have such a product and not being able to use it...
Thank you.

Please use virtual L3 switch.

Can you edit a routing table in your network router?
Most easy way is notifying gateway router address to far side network.
