Hi,

For TRB140 and TRB145 models, what is the maximum number of GRE, OpenVPN and IPsec tunnels? I did not see it in datasheet. Thanks.

Hi,

There is no specific limit of GRE,OpenVPN and IPsec tunnels being established simultaneously, but CPU load and Memory usage should not be over loaded while multiples VPN tunnels are up running and transmitting data.

You may also check the power consumption of TRB140 and TRB145 per following link:

https://wiki.teltonika-networks.com/view/TRB145_Power_Consumption

Running different VPNs parallelly may cause routing issue that VPN tunnel splitting/routing policy need to be implemented to resolve the issue.
