( Why does this forum force picking a product that is not in scope of subject matter ? )

 

I want to use Omada OpenVPN client to connect to my ( paid subscription based ) NordVPN OpenVPN server - however it requires a user name and password - which means that it will not connect .  So, I have tried using the NordVPN client and 2 other clients while adminstrating Omada SDN and I find that when I connect to the server ( no matter what protocol ) they stop my subnet access between vlans .

 

I have the OC200 on native LAN at 192.168.22.x and TL-SG2008P on vlan ' main ' at 192.168.44.x - my desktop PC is on vlan ' main ' .

Ordinarily from my desktop, I am able to ping the OC200 and access the controller via web browser and adminstrate operations .  ( Without ACL )

However, if I start up a separate stand-alone VPN client - such as NordVPN - or either of two other OpenVPN clients, suddenly I am not able to access the OC200 .

I have tried setting a Switch ACL from IP Group to IP Group and it does not solve the problem .

IP Groups : desktop 192.168.44.77/32 to OC200 168.22.55/32 .

No problem with access until I run the separate VPN client .  Does not matter what protocol the client is using or which program used of the 3 that I have .

That seems very strange that running a separate VPN would affect connectivity on SDN .

Any suggestion of how to regain access while VPN is running ?

I also have a question about being able to have a user name and password using the ER605 client VPN .  I will put that in another thread .

  @kablammy VPN clients often only open split tunnelling for the local network segment.  If your controller is on a different subnet, it is possible your VPN client is blocking it.  You should look in the client and see if there are options for split tunnelling or defining the local network subnets.

  @Alex789 

 

Thanks for the advice .

I looked at the options for all 3 OpenVPN applications and I see nothing about split tunnleling or defining the local network subnets .

NordVPN is a commercial, general consumer, paid subscription application and they don't provide any depth of detailed settings .  There are a couple other protocols that can be chosen and none of them resolve the problem .

The same goes for the two free OpenVPN clients - they are simplistic and offer almost no options .

I guess I might investigate the configuration files and see if there is a way to make pertanent changes to it to solve this problem ..
